I am into my 2nd week at 75 mgs. after doing 15 days on 37.5. I still have a lot of anxiety when I wake up, am nauseous and dizzy today. Is there anyone out there who has experienced these same side effects and how long do they last. Everyday I look for some little sign that Effexor us working, but so far It hasn't shown my anything that is even near getting better. I get so down thinking that this may never work and then I will have to go on something else and go through the wonderful withdrawals of Effexor. I need some encouragement badly as I am getting so fed up. thanks for reading.
