Welcome. You sound a lot the way I did this past January. Sick and tired of being sick and tired, exhausted by juggling my addiction with my family and professional needs, etc.
Post roll daily, post roll early, get to know your quit brothers. Refuse to cave.
Don't worry about messing up roll for a couple of days. Concentrate on your quit. It will get worse before it gets better, but your freedom is worth the price.
Proud to quit with you.
