Effexor Side Effects: Nausea, Headaches, and More

I started Effexor about 2 months ago and have had horrible nausea since increasing from 75 to 110 the past 2 weeks. I deal with chronic back pain as well and it hasn’t helped the pain. It has made my back pain meds give me more of a chilled out head high which I don’t like since I use them to function and when I’m too chill that doesn’t happen. I just talked to my doc about it and she said try taking the full dose at once at night (instead of one in the morning and one in the afternoon) to see if that helps. If it doesn’t then I’m going back to 75mg for a while. I have had nausea, sleep issues, extreme fatigue during the day, temperature dysregulation (really sweaty, night sweat, overheating, freezing) brain fog, head aches, nausea, and chronic pain before I started so honestly I have no idea whether the Effexor is making it worse, not having much effect or helping. I’m on it for bipolar so it’s pretty difficult to see if it really helps my mood because that’s constantly changing.

@Slater I was prescribed Effexor. I could barely get out of bed, and when I did I had to vomit or diarrhea, and then crawl back in bed. I didn't wait for my next Dr's appointment. ( I do not advise to do this for anyone, who take bipolar meds. ) I was desperate. That's ONE of the worst side effects. Having violent tendencies while taking Prozac is the other worst side effect of bipolar meds.
