first time i tried x was life changing, never bin so happy. but during that night, twice i had depression for a short duration. the next day and on i had no problems. second time i did a quad (4 in 1) and had a horible time. 5 minutes of a chill feeling then 4 days of depression. (shit pill?) my question is, should i try a single again or take half a single then the other half an hour after the effects kick in? (if they even do at all)
