Hang on in there, you will get better. I've had a couple of cheats on the diet too, we're only human. Don't beat yourself up about it. A bowl of ice cream isn't going to undo all the good work you've put in.
The diet and anti-fungals are great but are you doing the following too?
1) probiotics (Primal Defense or Threelac)
2) drinking plenty of water
3) colonics/enemas once or twice a week to keep your colon clear
4) Liver Cleanses (Dr Clark's or Andreas's protocol which are both on this site)
5) magnesium (which will calm you and make you feel happier)
6) exercising 3 or 4 times a week
