bad side effects from 5-iai ok swim and friend took a half a gram of 5-iai on saturday night, you will be able to read my trip report for the experience. So now it is monday evening and the come down from this drug is the worst swim (an experienced stimulant user) has ever had. my friend however had it even worse!! insomnia is relentless, feelings of complete detachment from any feelings and others. strugging to speak, no feelings of hunger, continued jaw clenching up to 24 hours after last dose. I am coping with this and managed to go to work today however my friend has had all of these side effects plus panic attacks, heart palpitation, hallucinations to the point where she was seriously think about going to a&e. swim just hopes that sleep will happen soon so that she can wake up feeling at least able to function. in swims oppinion a dangerous drug to the body and mind and spirit.
