I'm a month post surgery (yesterday) and just this week I've started having nausea. It's completely random. After eating, on empty stomach, when I drink water, or any other liquids. I'm losing weight and feel great about that. I'm following the program and my guidelines. Anyone else have this problem start up? I haven't had problems till just this week and haven't really had any of the typical reactions to foods my body isn't ready for....I've been very careful adding stuff.
