Just get lost in the moment, or fight boredom mentally, it will send you to sleep.

There is nowt good about being stoned, and bored, as I trend to repeat the following words in my head constantly;

'I'm bored, what can I do? I don't wanna do that, its shit, I wanna do this but can't. Aww fuck, I cant be arsed doing nothing, HELP!!!'

Other than that, I don't know. Go annoy someone.
