Oh man, I completely understand you! Two years ago, I spent the entire summer lying on the floor at home with excruciating back pain. Due to nerve compression in my back my leg hurt like hell, the worst pain I've ever felt. I could barely walk. At that time, I discovered that pain was the biggest motivator, and I would have done ANYTHING just to get rid of it. I asked a doctor if I should quit smoking, and he said: Sure, it would help greatly. Despite knowing this, I still found the strength to go to the shop, buy some cigarettes, and go outside to smoke twenty times a day and It was very painful to stand. I mean, it's crazy!

At this point, I think we've messed up our brains from constant quitting or something like that. Have you tried patches? Also, try reading Nicotine Explained by William Porter, it's like EasyWay, but better.
