I had a day like this today and it ended up in a b/p. I've been in a pretty bad cycle though, but on the 'healthier' days I seem to cope better.

Honestly I can't seem to stop those craving days, sometimes exercise can help. Some of the meds I take increase hunger which makes it worse argh. It'd be so much easier if our bodies only wanted good food in us, and smaller sized meals. I'm not much help, but I can relate.
