I currently take 10mg per day. I started with 2mg for about a week, then 5mg the second week then up to 10mg on week 3 or 4. I have been taking the 10mg per day for about 3 months now. It took about a month for my body to get used to it but I really started to notice more of a difference after about a month and a half. At first the side effects where fairly strong, I experienced blurred vision, soreness in my joints (especially my knees), confusions and difficulty thinking. The soreness got pretty bad the first month so much that I skipped a few days and almost considered stopping. But I decided it would be in my best interest to keep taking it and I'm glad I did. Now I don't experience any of those side effects. Although, I take it at night and I don't drive after taking it just in case.
