Stay off any drug even coffee tim to take care of your life. If u have any history with coke take some benadryl. any history w/ meth take risperdol. normal onset at the end of puberty take zyprexa. if thats not enough add lexapro if you dont need lexapro it will make u fill bad right away. If and only if your on what i mentioned you will be okay w/ coffee. maybe a beer. but as soon as you get higher than the meds there is a chance of feeling bad everybodys different. The meds i mentioned wont need to be discontinued if you have a slip up. everybodys different.The meds I mentioned u will feel better kind of quick. Like me I was stupid and used everything and now all my meds have been raised. be smart. Feel better:-)
