"started taking venlafaxine er a year ago for anxiety. started at 75mg daily and am currently on 150mg per day, and have been for about 8 months. it has helped a ton with the anxiety! while i am not completely clear from anxiety, it is much much better to handle. i did not gain any weight whatsoever. i do notice that if i forget to take it i feel a bit nauseous and lightheaded so i have set an alarm on my phone. i take both 75mg pills at one time so that it&#039;s done for the day. all in all, i would recommend!!"
