This does not happen all the time, rather on occasion.
I will wake up in the morning and when i get out of bed my stomach starts doing this weird cramping thing (no other way to explain it). My stomach rolls and I feel like i'm going to get sick. If i ignore it and don't eat anything (which seems to help a litle bit), it can and will escalate into full abdomen cramps.
This is something that has been going on for several years. It only happens when i have to get up early as well.
Any ideas? I've tried tracking food among other things, none of which hasn't helped.
