why do I feel so groggy and lack of energy when playing??

[7_toolz]

Hey guys,

Recently I turned pro to play sng's for income and this is my 3rd week into playing. During my 1st 2 weeeks I felt normal and was energized. However, lately I have been feeling quite groggy and lacking energy. Especially a few hours after I eat, I feel like napping again and am falling asleep in front of the computer

I usually go to sleep at around 4 or 5 am and wake up around 12 or 1pm.

I am not the healthiest guy: daily smoker, 30 pounds overweight, and I eat out everyday, and don't workout.

I know working-out helps and I definitley plan on eventually going to the gym. But does anyone have similar problems? Any products to recommend? Any personal routines to help keep you fresh during your poker sessions? Any advice in general?

The one thing that bugs me is that I never really had such a problem, why now?

- thanks!
