I went down to 95lb from starving for about 6-7 months while alone and nutty in toronto,2005. I certainly never smoked nor drink then.
starvation IS the cure and brings about plenty of visions.
Be kind to yourself for real: you will all go pretty nutty.
I say, dearest people: enjoy being nutty. And get to know your own fabulous mind, thubten, when under hardcore starvation.
