Its been 7 weeks post op.and I have only lost 18 lbs. I started this journey at 271 I went surgey at 238. Today I weighed in only at 220. I guess I just need to take realization that I might be slow looser. How much does intake of water effect weight loss or having bowel movement? These two items I have been struggling with. The doctor says im doing fine that if I work on water intake that my weight loss will Improve. Guess sometimes you need hear what others say.
