I only take two vivarin if I am tired and need to stay up you don't want to take too many caffine pills.
Why not just drink some strong coffee? Better than swallowing down a bland pill. This way, you can enjoy yourself while drinking AND later on when you get a bit of a buzz. If that's what you want. Or you could always go for a run. Endorphin-rush--sometimes there's just nothing better (not to mention cheaper). We'd all be happier if we went for a good run everyday. Even after the drug-like effects of the endorphins wore off, we'd have a healthier body and mind to look forward to in the future. Better self-esteem from not being so fat and lazy, a sense of strength and accomplishment, et cetera.
doses of cafein at or over 10g can casue seizures, respitory failour and death. it varies though, some people are more sensitve to it than others. long term caffein over use, of more than 1g/day can casue major health problems. some people can have problems at lesss than 250mg. signs of cafien overuse 1. restlessness 2. nervousness 3. excitement 4. insomnia 5. flushed face 6. diuresis (i dont know what this is eather) 7. gastrointestinal disturbance 8. muscle twitching 9. rambling flow of thought and speech 10. tachycardia or cardiac arrhythmia 11. periods of inexhaustibility 12. psychomotor agitation (????) this info is from , http://www.drowning.com/caffeine.html
What happens when you overdose? From Desk Reference to the Diagnostic Criteria from DSM-3-R (American Psychiatric Association, 1987): Caffeine-Induced Organic Mental Disorder 305.90 Caffeine Intoxication Recent consumption of caffeine, usually in excess of 250 mg. At least five of the following signs: restlessness nervousness excitement insomnia flushed face diuresis gastrointestinal disturbance muscle twitching rambling flow of thought and speech tachycardia or cardiac arrhythmia periods of inexhaustibility psychomotor agitation Not due to any physical or other mental disorder, such as an Anxiety Disorder. Basically, overdosing on caffeine will probably be very very unpleasant but not kill or deliver permanent damage. However, People do die from it. Toxic dose The LD_50 of caffeine (that is the lethal dosage reported to kill 50% of the population) is estimated at 10 grams for oral administration. As it is usually the case, lethal dosage varies from individual to individual according to weight. Ingestion of 150mg/kg of caffeine seems to be the LD_50 for all people. That is, people weighting 50 kilos have an LD_50 of approx. 7.5 grams, people weighting 80 kilos have an LD_50 of about 12 grams. In cups of coffee the LD_50 varies from 50 to 200 cups of coffee or about 50 vivarins (200mg each). One exceptional case documents survival after ingesting 24 grams. The minimum lethal dose ever reported was 3.2 grams intravenously, this does not represent the oral MLD (minimum lethal dose). In small children ingestion of 35 mg/kg can lead to moderate toxicity. The amount of caffeine in an average cup of coffee is 50 - 200 mg. Infants metabolize caffeine very slowly. Symptoms Acute caffeine poisoning gives early symptoms of anorexia, tremor, and restlessness. Followed by nausea, vomiting, tachycardia, and confusion. Serious intoxication may cause delirium, seizures, supraventricular and ventricular tachyarrhythmias, hypokalemia, and hyperglycemia. Chronic high-dose caffeine intake can lead to nervousness, irritability, anxiety, tremulousness, muscle twitching, insomnia, palpitations and hyperreflexia. For blood testing, cross-reaction with theophylline assays will detect toxic amounts. (Method IA) Blood concentration of 1-10 mg/L is normal in coffee drinkers, while 80 mg/L has been associated with death. Treatment Emergency Measures Maintain the airway and assist ventilation. (See Appendix A) Treat seizures & hypotension if they occur. Hypokalemia usually goes away by itself. Monitor Vital Signs. Specific drugs & antidotes. Beta blockers effectively reverse cardiotoxic effects mediated by excessive beta-adrenergic stimulation. Treat hypotension or tachyarrhythmias with intravenous propanolol, .01 - .02 mg/kg. , or esmolol, .05 mg/kg , carefully titrated with low doses. Esmolol is preferred because of its short half life and low cardioselectivity. Decontamination Induce vomiting or perform gastric lavage. Administer activated charcoal and cathartic. Gut emptying is probably not needed if 1 2 are performed promptly. Appendix A Performing airway assistance. If no neck injury is suspected, place in the "Sniffing" position by tilting the head back and extending the front of the neck. Apply the "Jaw Thrust" to move the tongue out of the way without flexing the neck: Place thumb fingers from both hands under the back of the jaw and thrust the jaw forward so that the chin sticks out. This should also hurt the patient, allowing you to judge depth of coma. Tilt the head to the side to allow vomit and snot to drain out. From conversations on alt.drugs.caffeine: The toxic dose is going to vary from person to person, depending primarily on built-up tolerance. A couple people report swallowing 10 to 13 vivarin and ending up in the hospital with their stomaches pumped, while a few say they've taken that many and barely stayed awake. A symptom lacking in the clinical manual but reported by at least two people on the net is a loss of motor ability: inability to move, speak, or even blink. The experience is consistently described as very unpleasant and not fun at all, even by those very familiar with caffeine nausea and headaches. taken from http://db.uwaterloo.ca/~alopez-o/Coffee/caffaq.html#WhatHappens
hmmm it wasnt for the buzz mr 15 yearold i know running is good i love to run... ive been having knee problems so i cant really run at this point in time.... yeah thats what i figured... it was just for the nervousness and crazyness ... quite odd
i used to take lots of caffiene pills to stay awake during school, and then me and a friend figured we may as well have fun with it. the most i had was four pills and that night after it wore off i felt horrible. my heart was beating really fast and i felt extremely nauseous, it was hell. i just drink those energy drinks now if i wanna stay awake
I just made about a gallon of iced tea, and i've been sipping on it periodically. Tea is the mild and sophisicated way to consume caffeine... Quite good, eh what? Rather!
