I had my sleeve done March 18th, so about 2 weeks out. I was like "wow" this is a lot of Fluid to get in. I was doing the shot glass every 15 minutes, but started dry hieving, but nothing coming up, the nurse told me to slow down on fluids, I did and that took care of it. The last few days I had been getting light headed... kinda foggy funk... well I called the Dr., he asked what color is your urine, I said about apple juice, no no he said, I was doing about 48-50 ounces of liquid, he said not enough, he said minimum 64 oz. try to get close to 90 oz. if ya can, I was dehydrated!, then bam! all gone.
I now have no problem drinking 80 oz. I know it can be hard, but drink, drink, drink!
Wish you all the best!
