Over the holidays I was feeling really bad mentally (I won't get into the specifics) and they put me on this dreadful drug called Haldol which made me feel like my joints were on fire and my thinking was severely impaired. Frankly I don't even know how I made it through since I remember feeling completely zombiefied while on it. They took me off it one week ago and put me on a far superior and less harmful drug called Effexor which they say has to build up in your system before it really starts working. Still I've been taking the Haldol from Jan 1st up to a week ago so I was wondering how long it takes for that drug to leave my system completely. Anyone have any knowledge of this? Any pharmacists here? Boy that drug nearly killed me...scares me just thinking how I was on it.
