I am not on them now thank goodness, but I have always wondered if the withdrawal symptoms I experienced when coming off of anti-psychotic drugs such as Lithium and others like it being similar to those experienced from someone coming off of Heroin was just something I experienced or did others as well. I would be very interested in hearing other people's thoughts and opinions on the subject. For me, when the drug is leaving my system I am tired, nauseated, ill, etc. I feel like I have been a Heroin addict for years, regardless if I have never touched the stuff or not. The symptoms made my life a living hell to be honest with you. Does anyone else have any experience that was similar?
