E.W.
I was on Effexor for a while and decided to get off of it (was going to start trying for baby #2 and wanted to be drug free). If you are going to switch drugs you need to talk to your physician about it DO NOT do it cold turkey. It is a nasty, nasty drug! I wish I had done research before taking it because I had horrible withdrawal symptoms. My doctor slowly weaned me off but it still took months to get out of my system. One of the withdrawal symptoms that I had (that is not normally spoken about) is brain tremors, they were like sharp zaps in my head. It was very scary and freaked me out a bit. You can read more about it here:

or you can also just google Effexor and brain tremors. The best advise I can give is be sure to get off with your doctors help, wean yourself off slowly, and be ready for a long withdrawal process. Good luck!
