Sorry to hear that family sounds like a rough night yep drinking will do that to you belly and brain problems that could throw your body off for a few hours making you feel weak and in need of water the next day that's part of the reason you feel that way but once you start to hydrate your body it starts to come to feeling better and slowly you can start your day and thats what I hate about drinking to much in one sitting but it do not effect all in the same manner all the time some can take more than others but over all becareful of how you treat your body we only get one thanks family
