honestly. i've always slept like crap
my wife makes fun of me for it.
I was always a light sleeper, like if a furnace kicks on on in the other side of a house, i'd wake up.
however, i took chantix to stop smoking and i never honestly recovered. that was 7 years ago or so now? when i was in the middle of chantix, i would wake up after an hour and be awake all day, some nights i wouldn't sleep.
Once i stopped drinking, it did take a bit get to get back into a normal habit of sleeping better. But the drinking didn't start my sleeping issues
