If my sickness doesn’t go away in a day or two I’ll pound straight whiskey until I pass out. It has worked several times for me, as crazy as that sounds. I’ve heard people say drink warm whiskey but I drink it on the rocks. If it’s pain you’re trying to get rid of it’s tough to beat some indica edibles and ibuprofen. Works great for sleep too. I’ll never take a flu shot again. The three times I have I’ve got sick and I just about never get sick.
