My Dr does blood work on me every year, my diet however tends to fluctuate depending on how I'm feeling and unfortunately I was unable to do any serious exercising for a few years because of a knee injury during college soccer. I've just gotten back to the gym and unfortunately it makes my mood take unwanted swings upward. Trying not to overdo it but I have really good muscle memory and hour cardio feels like nothing. My Dr suggested 5-htp one time but in the one week that I took it regularly, I didn't sleep 3 of the 7 nights and felt a little coo-coo for cocoa puffs.
