You have the right idea, Dan. If you fall, get right back up. And yes, the "Big Guy" will give you the strength. I used to do some counseling work with addicts of varying substance including heroine, meth, crack, etc. at to a soul the all said kicking nicotine was the hardest of all. When you've kicked this one know that you can do anything with the right motivation and a little help from above---AND from your friends!

And for playing the guitar, do it! The more stuff you can do without the smokes that you used to do WITH the smokes the more certain your victory!
