Looks like there are several people starting met now or sometime soon. I took my first dose this morning (my doctor started me on 850 mg) and really haven't had any side effects so far to speak of. I do have a headache, but not sure if that's a side effect of the met or due to the fact that I didn't drink any coffee today!
Good luck to everyone! Its great to see that there are other people in similar situations and have some of the same worries/concerns.
