Diphenhydramine Alone and Mixed Heroin IV
My intent in writing this report is there is very little accurate info on the net and I consider myself qualified to share my many experiences as a heroin addict and a insomniac with a view towards harm minimisation. The substance is called Diphenhydramine a anti-hystamine commonly found in benadryl the expensive version of it is called Unisom and many swear this is far stronger than the generics which are a third the price. I find both are the same strength generally at 50mg.
The heroin we get on this continent is rubbish so many use "Unis" as a potentiator that is mixed generally 2x 1 point of heroin, But I've know of people to have as many as x5 Unis in a shot. As far as safety goes I NEVER heat them up as thats a sure way of losing a vein, imagine hot wax going into much cooler blood. Oh and I really don't want to miss either. Despite the aforementioned I myself and many known to me have used these blue gel pills for years.
What I can expect is cognative impairment and lost veins. I add plenty water say 10ml per pill. I have also taken high doses orally and I cannot estimate strength. But at say 500mg I expect loss of depth perception and trouble walking to bed, turning lights off etc. I dont think I have a tolerance to it but definately never burn them and use plenty water and they are relatively safe in the short term, long term I have known people who claim to be addicted to them and they do seem to have that aspect going. But really if our gear was stronger I dont think Unis would have the appeal they do.
