sucked my thumb until a teenager

I was a thumb sucker until I was 12 (only at night). My parents tried the nail stuff, tabasco sauce, band-aids, etc. Nothing worked until I decided I didn’t want to be a teenager sucking my thumb. When I got serious and self-motivated, I wore a tight arm-sleeve as a reminder. It took a week or two of having problems getting to sleep, but I finally did it (my teeth could be better, but they aren’t messed up too much). I’ve heard of people since who thumb-sucked through college and until marriage. I think no matter what age the person has to be ready.
