I've read the posts here about Effexor XR, and I guess I'm just posting for a little one-on-one support. I've just started taking it for PTSD, major depression, and anxiety (helping my IBS-D will hopefully be a bonus if I can keep the constipation from being a huge problem, which isn't looking easy to do at the moment). I've had 4 days so far, 3 at 37.5 mg and 1 at 75 mg, and I just feel like I'm losing my mind. The very first day, my mood was great; the usual brain synapses that relive trauma after trauma in my mind didn't work - I mean I tried to access them and just saw them as vague memories instead of reliving them as I usually do, which was just amazing. It must have just been the shock of the drug hitting my system for the first time though because it's been downhill from there. Right now I don't know that I feel much better than usual (if any), and the side effects are just killing me. I'm exhausted, it's hard to focus my eyes, I can't concentrate, my head weighs more than a bowling ball, and I'm nauseated. I'm supposed to stay at 75 mg for a week and then go up to 150 mg, and I'm having a hard time telling myself that I can stand this until the side effects wear off.More than anything, I want to feel mood-wise the way I did the very first day that I took it (side effects-wise, I felt completely stoned and a little disoriented!). I think that is a lot more what "normal" people feel like, and it was like heaven for me to feel.Someone please tell me that I'm going to make it through this and have a chance at feeling that way again.
