How can I stop sucking my thumb at night?

i used to suck my thumb since i was a baby also and i just stopped...when i was 11 or so....me and my mom and my dentists had been trying for years to get me to stop and nothing worked. my mom made me sleep with socks and gloves on but i would take them off in the middle of the night and she also tried hot sauce....but that was a bad idea...i cant eat anything with out hot sause any more....but eventually i just stopped on my own. so if none of those things work for you...then just wait a little bit...its just a phase [a really long one] and it'll go away
