If you have some bad lasagna it can give you a pretty rough time for about 24 hours. It’s not unusual afterward for it to take ages before you’re able to even look at lasagna again. If you go on a bender there’s a pretty good possibility it’s going to make you feel the same way as the lasagna did for about the same length of time, but the chances are you’ll be ready to drink alcohol again within a couple of days. Why is that? Why does our body “learn” to protect itself from spoiled food that makes you sick but not from too much alcohol which does the same?
