anxiety and stress
"I have been on Effexor XR for approximately 7 years now. I was started off at 75mg and have since been raised to 225mg over the years. I have had good results on this medication. One downfall is the terrible withdrawals that I experience if I miss a dose. These effects happen within the first couple of hours of not taking it. Terrible headache, foggy feeling, and extreme eye sensitivity. Within a day of a skipped dose I become agitated, argumentative, and defiant. I do not look forward to switching from this medicine to a different one, which my doctor has suggested, due to the withdrawal symptoms."
