Hi berries I was on Effexor over ten years ago for 24 months(about 150mg from memory) and my personal experience wasnt that fantastic(mixed feelings)I can honestly say from my experience that it initially had an impact on me.It turned me from a recluse to an extrevert. I felt invincible and it felt like I was runnin in a high gear all the time, couldnt stay still strolling the streets night and day,and eventually I had to stop as I became irritable and hostile towards many people who were in contact with me.But thats my personnal experience and like always claim and my doctor said not every individual experiences the same symptons.Please I would like any feedback on Effexor as I have considered possibly trying it again as there have been some enviromental changes this time round since I first tried it.
