No Energy...

The good part is you're probably sweating a lot and getting out a tremendous of formerly fat stored toxins which may be dragging down your mood and energy level too. 

It also just might be your body's common sense reaction to extreme heat or both. 

Youre only ninety days out ? Your pouch and insides are still healing too .. I think lower energy is normal. Soon your new lighter set point will have you bouncing from store to store!
