I had my sleeve 12-jun-13. I have only lost 40 lbs. because I have not been able to exercise. I was so dehydrated, I was having dizziness,low b/p and fell-getting staples in my head after passing out and falling on the tile flood. .My cardiologist changed my meds a few times times over the phone-no results. Went to an appointment, found out I was dehydrated. Dr. Advised me to drink coconut water, within 3 days I felt better than I have in a month. If you are dehydrated coconut water is the best better than Gatorade, only draw back it is quite pricey.

You may want to try going to a Sam's club or Costco if you are near one. They usually sell it by the case? You can also try Amazon.com to see if they have it. Good luck to you.
