Quick fix for a hangover = healthy banana milkshake
1 cup skim milk
1 scoop light vanilla protein powder (like Muscle Milk light or the Jillian Michaels light one at Walmart, and you can use chocolate if you're really feeling naughty!)
1 sachet of sweetener (i like stevia)
1 ripe banana (i freeze mine in saran wrap.. the last longer)
a few ice cubes..
Total awesomeness, exactly like a banana milkshake. DELISH, cheaper and good for you
Maybe then you won't feel guilty. One thing I didn't notice you saying was how much water you drank... water is crucial to weight loss. If I don't drink enough in a day, my body WILL let me know it by retaining water. Keep at it, don't get down, give it another week minus the booze. (My fave mixed fruity drink has well over 500 calories...3 of those equals what your total calorie intake should be for the entire DAY!!). Find some lower calorie drinks for the next time you go out. Stay away from the fruity ones... things like vanilla vodka and diet coke, or a wine spritzer, or a my fave, captain and diet coke are lower in calorie and you still feel like you're splurging
