Bull sh!t. Since I quit last January I've gained more than 30 lbs.
I ballooned to over 200 lbs when I quit smoking. I got breathless just tying my damned shoes.
I was grouchy as hell and my free floating anxiety was off the charts.
I started smoking again, lost the weight and feel so much better now.
My joints no longer ache just walking across the room.
I gained 15. Hard to keep off.
