Limiting booze. Especially if you are home alone. Alcohol will really bring out your blues even in small amounts if you are already down.

Eat well. Really focus on fresh fruits and veggies. Limit simple sugars that spike your insulin levels. Swweeten with honey rather than white sugar, limit sweets overall. Eat complex carbs not simple carbs.

Lots of varied exercise. Today was a long mountain bike ride followed by a trip to the driving range.

Get out there with friends and family even if its something your not that interested in, don't spend too much time alone.
