The morning after drinking really is not a good time when you think about it. First you wake up like...
Then you realise you've got to make a quick dash to the bathroom for one of two reasons:
1) Remember those drinks you had? yeah, they're making their way back up...
2) you've got to go number twos, like RIGHT NOW.
If you've every wondered why you suffers from that second reason so often, it's all because of the ethanol in the alcohol you were drinking. Dr. Kathlynn Caguiat said:
Alcohol can increase gut motility and it doesn't get broken down before it reaches the colon, where bacteria feast on these, resulting in bloating and diarrhea
Dr. Urvish Shah also said the more concentrated the alcohol is, the worse that situation in the bathroom is going to be. Malt liquor is the worst cause of 'booze poos' followed by beer so best keep clear of those and instead, drink wine or clear spirits.
