If you could explain more on how it "fucks you when you're sleeping", it would be easier to understand. I know I hardly ever feel like smoking when I'm sick, and only when I start to feel better do I even consider it. It has always helped my upset stomach when recovering from a flu bug, so maybe what you have counter-acts with the weed and you feel the brunt of it? Sometimes you just need a break to get better. Weed doesn't solve ALL of the world's problems, only half!

I dunno really, but in any case, feel better
