I was on it several years ago at 200 mg. I am back on it now, ramping up the same way you are. It was helpful to me in the past when I got help for a deep depressive episode, kept me from being manic from the AD and also gave the AD a little kick at the same time. Interesting stuff.

The only side effects I have are intense headaches with each increased dose, but they only last a day or so, and muscle aches/fatigue with higher doses that also goes away.
