Yeah I got the same way. When I stopped smokin' I couldn't eat a lot at all The first two nights I couldn't get to sleep. I would wake up at like 12 am and never get back to sleep. I never did have that much of an appetite that's why I like weed so much when it comes to eating because it always gives me an appetite and make food better. I know I should take another break because...well I need it but I really don't want to end up waking up from not being able to get sleep and I don't want to get sick every time a take just a little bite of food. After a few days everything is better but the appetite prob for me is still there.

btw you mentioned being winded walking up the stairs..well cig's don't help .
