I have been off Effexor completely for 3 months. Had a terrible time getting off, but was successful

I'll start with the pharmaceutical suggestions, which tend to be a bit more "reliable" then move on to some natural remedies that have helped me personally.

Remeron works great for anxiety in a lot of people. It doesn't have the side effects of SSRIs and SNRIs. It's main side effects are drowsiness (you take it at night and sleep like the dead), and increased appetite, which can cause weight gain if you don't watch your diet. I've heard, anecdotally, that it is very difficult for some people to get off of.

Another option is gabapentin (Neurontin). This works very well for anxiety in my experience.

As far as dietary supplements, I've found magnesium, vitamin B6, vitamin D3, Taurine, Tyrosine, kava tea, and threonine helpful. Results may vary, and there aren't many good scientific studies to support these. That said, many people have reported benefits from these supplements. They're all available on Amazon, and possibly in stores.

Hope this helps, and you get to feeling your best soon!
