I just do some Vitamin B pills and down an alka seltzer, which helps a headache and upset stomach. Then, I eat something that won't upset my stomach (in this instance, a banana and some toast). Then I take a Centrum and drink some juice. After that you should be super.
I just did this this morning. I was hurting from last night really bad. That'* what I get when there'* a 36 pack of MGD for only $14.99.
