I'm having serious issues with this concept right now. I don't know the difference between nausea and hunger. I "guesstimate" when I'm hungry by calculating the last time I ate something substancial. But because of the nausea, I lose my appetite - so it only gets worse until eventually it seems to *magically* go away and I can eat, but that usually takes a good 12+hours of pure misery.
Anyone else have trouble with this?
