I am not TOS, but RSI -

I was given Effexor today to start for pain and tramadol for break through pain. I dont have depression issues - was/am trying to find other folks with RSI issues/similar to see how they liked this med and if they felt it really helped any? I see alot of folks that take this gain weight - and trust me I dont need more weight on me... so just curious. I was told at a low dose I shouldnt gain. Dont see too many RSI folks when I google it take it..... so thought I would ask here since this board has been a help in the past - and here .. a post on drugs.. thought I would try. Thanks
