40 years, male. They felt that the lack of energy, comes from a time (6-8 months?). He hit hard in the last 3-4 weeks. Frequent yawning, tired, feel like I'm in a fog, etc ... Difficulty concentrating, forgetfulness, no energy to do something. A little more weight (10-15 # 's). Exercise 2-3 times per week to run (3-4 miles or bike 10.12 miles).

Only the search for the magic "for me, with a few extras that could bring him to me. Suggestions ??????
