"If so, what works best for you? "
What an interesting question. As everyone knows an alcohol hangover needs time to get better. That said, cannabis can help get you over the hump if your hangover includes a headache and nausea. The nausea can stop you from eating and eating definitely helps speed up the recovery process. Cannabis typically will allow you to start eating again. It can also help with the associated headache, which can be so terrible. Unfortunately, alcohol is literally a poison and if you drink too much your body is reacting for a reason. Cannabis helps mitigate the symptoms. Hydrate, take vitamins, eat, sleep and waiting it out is what really helps.
