I actually was the same like 2 years ago when Chase came on board with their INK cards and I discovered the miles game, I was crazy just to fly LH F. I flew like 12 F long haul segment (even took along my children a couple times). Killed the urge, now I'm mostly selling miles.
Don't shove your urges under the rug, let it out, book your awards and enjoy it while it lasts, and it will cool off eventually, then you'll cool down.
