DEHYDRATION!!!!!!!

Help!  It seems I have a hugh problem with dehydration - its to the point where I actuallt pass out in public places, concerts, amusement park, etc... amd I was wondering is it due to the fact that out pouch can only hold a few ounces of liquid and perhaps I am sweating out more than I take in???  Any help would be appreciated.  (My PCP tells me not to take my blood pressure pill when I go to concerts, but I think it might be more involved than that.)

It seems strange to me that your pouch can only hold a few ozs. of water at a time this far out? Are you always keeping your water with you and sipping all day long? Maybe you should see your bariatric dr?
I know that I can't drink cold beverages anymore,or it's hard to get in, everything I drink is room temp.

My biggest danger is dehydration as well and I tend to have water handy at outdoor events and drink constantly.  I'm too sure what the deal is, but it is an issue and I live with it.  For me tho, the dehydration feels more like a drugged out stu*****t dizzy, etc.

The other thing I wonder is I used to have a BP pill but once I lost weight I no longer needed it.  In fact, it was making my BP too low leading to dizzy feelings especially when standing.  Since I longer take the pill, I no longer feel that way, tho.

I drink about a gallon of water a day and feel my lips drying out if I drink less than a half gallon...I depend on drinking alot of water..

How much water are you drinking? could it be low blood sugar that's making you passout?
