Hi, if you just started, how much are you taking now?
I started with 2 x 10 mg a day and had side effects only the first week or less, like stomach pains and muscle's being weird.
Whenever I had to take more, I did this very slowly to get my body used to it.
Now I'm on 7 x 90 mg without any side effects

Fredh's advice is a good one, especially of you have stomach troubles.
