I can’t say whether or not you get schar, but I do know that wanting to want is a huge step.
I once had a friend who was OTD (the real kind, not the coffee room kind). One time we were sitting on a curb on shabbos, he was smoking a cigarette, and he was pretty intoxicated so he was being really honest.
So he says to me, “I’m sitting here smoking this cigarette on Shabbos, and I really want it to bother me, but it doesn’t.”
That guy is a huge Talmid Chochom now.
