Hey, don't want to beat a dead horse.........but I need some advice!

I got off Effexor in about Feb. of this year. I am under waaaaay too much stress and it seems I am getting "under the weather" again! So, I am back on Effexor. My doctor put my back on 150 mg (he didn't start me off slowly like he did the first time). I am having some side affects that are keeping me from functioning normally. I am dizzy, nauseated, sleepy, and am extremely thirsty. Will the side affects subside like they did last time I was on this medication?

Anyone have any experience with this drug? When I weened off last time, it was extremely difficult for about 3 weeks. I didn't want to go back on the meds, just didn't think I could cope without it yet!
