Depends on how you slow you 'sip' it. like if you take an hour to drink the bottle, you wont get as strong as a high, like you wouldnt reach as high of a Plateau, but the high would last longer. I would advise chugging it, just get it over with (unless you have a weak stomach, you could puke, try to do it on an empty stomach) Btw, how much mg is in the bottle? just curious i plan on dexting today to lol. PS make sure there is ONLY Dextromethorphan in it... I'm sure you already know that, but just making sure.. hahaha
