I have been dealing with unpredictable nausea with dry heaves for about a year. Now, within the same day, I go from ravenous hunger and wanting to eat everything in sight to dry heaves and back to starving. It feels very much lille pregnancy. I had a hysterectomy last year for PMDD. They left one ovary. I'm trying to determine if I could still be having reactions to ovulation but symptoms seem to frequent. I'm also diagnosed with Panic DO and Major Depression. It's it all psychological?
