I manage very well but I have my moments where I just need to sit down. Sometimes I push through when I know I should be sleeping as well.

However, be that as it may, my diet has allowed me to continue for a long time without much set back. I feel like I'm getting stronger and more adapt at it.

The biggest factors were cutting out bread/buns/pita, and cutting back on meat. In retrospect these 2 items fill me with the most stuff that takes a long time to burn off.

The best I felt ever was when I was on a strictly vegan diet. Small regular meals, quick and easy to digest, but I couldn't get enough protein so I throw in lean meat and eggs. You have to feel your body out, it will tell you what it likes.
