Regular Ibuprofen use I have found that having 2 caps of advil (total 400mg Ibuprofen) before playing does relax the big muscles - back, quads, hamstring, shoulders - and makes playing much easier. I tried this because I have had chronic knee problems for a long time, and 400mg of Ibuprofen really helps with that. I don't take anything after playing. Also, this dosage does not cause me any stomach problems (no irritations, etc). I am thinking of doing this regularly as a preventive measure. What I would like to know is whether this will result in any long term adverse effects. Thanks in advance!
