staying quit???

I am on day 215 now

As far as quitting my only problem is the sometimes string urges to smoke

I have learned that if I ignore them they will go away fairly quickly

but I still hate them

I worried that by not coughing up any dark substances from my lungs that I may have COPD,,, if I do,,I do,,, cant do anything about it at this point so have stopped worrying about this

my worries now are

My weight,,,gained over 10 kilos ,,, am eating less and cant seem to lose

my mental outlook

3 months ago I flipped out on a friend and almost lost the friendship,,, nothing violent but lot of nasty verbal abuse

a week again,,,happened again

I feel like such a complete idiot

dont know if it is the quitting smoking or if I am turning into a miserable nasty old man (i'm 70)

either way I need to understand and change this behavior

asides from all of this the staying quit has been going good

and shooting for 8 months now
