I'm on day 2 of 40mg of Metermine. I had little to no side effects. A slight dry mouth, and a little headache last night (which I am prone to). I didn't feel energised but I did feel more relaxed as I think my mood was increased. No moodiness at the end of the work day. I'll see what today bring, has anyone else experienced better moods from this or do you think it's the fact I feel more in control of my weight loss?
