You may be dehydrated. Pinch the top of your hand and if the skin doesn't go back down try to get more fluids in. If you can't then you may have to go to the er. Is your urine real dark?
I think you're being to hard on yourself. I was sleeved April 15th and have lost 51 pounds since April 1st (1st day of pre op). I was told 5 pounds a week loss is average.
All I can say is WOW!!!! What a life transformation!! I am having the sleeve on April 15th. I am very excited just nervous about the two week liquid diet prior to surgery.
