I was on prozac and risperdal for 2 yrs, the lithium was relatively new, bout 6 months (switched over from tegratol)... The worst (sweating, hallucinations, agitation, skin crawling etc) was over after about 2 weeks, they lasted a bit longer but were easier to contend with.

Nobody can say for sure how long withdrawls last, metabolism, med half life and length of time you took them are some factors that come into play. After 6 weeks I saw my gp who did some bloodwork and general check-up and he assured me that there was no more psycho active drugs in my bloodstream, this is why I don't understand how some say they went through months of withdrawls Like, are your kidneys broken or something man???
