Hello,
I was sleeved on the 28th and also suffered from extreme nausea. I had the dry heaves for the first couple of days. I was able to correlate the worst of the nausea I was experiencing with the pain meds and reaction to anesthesia. Thankfully, day 4 came with no nausea and the ability to drink and eat. I hope your nausea meds worked. Hang in there!
