I've had a couple of bouts of sudden, brief, intense nausea over the past 3 days. In googling about possibilities, I'm wondering if it's a sign of gall bladder trouble. I tried the Murphy's Sign test, and I definitely seem to have some tenderness below my bottom rib on the right hand side. http://en.wikipedia.org/wiki/Murphy's_sign
I read that drinking apple cider vinegar (1 tbs in a glass of water) can help, so I did that, and it really did seem to alleviate the feeling, and it also tasted really refreshing, as if my body needed it.
Zone diet on and off for several years....worked, but too much focus on exact meal composition
Primal since July 2010...skinniest I've ever been and the least stressed about food
