Hi Mike, welcome to the club Hang in there, the third day is the worst, from there it is all good. Cravings will never leave you, but they get milder and milder. Cold turkey is the right thing IMO, did it as well, that will leave you with no soft excuses.
I hope you make it I used chewing gum (regular peppermint) in the beginning to cut that urge, I would not go to chocolate as a substitute, you will gain too much weight from that. I quit 35 years ago, never lit one up again
If you feel like hitting the wall, just post here with your thoughts, it might help to get some encouraging words
