My energy levels are decent, although I work overnights so it's tough to judge. Motivation to work out has never been there my whole life, but I do usually have the energy to complete a heavy 3x5 and not feel like death. As for anger/depression, I think I'm mentally healthier than ever. I'm still a bit of an emotional guy, but I am very good at keeping things under control.
Let me know if you do find out any specifics on yourself, and good luck!
EDIT: Oh, and as for GI issues, I used to have horrible heartburn and reflux (taking 3 max strength Zantac a day, plus antacids) and that's better now. I wouldn't doubt that there are still some concerns though.
