This are methods I tried when I broke up, works for me 
1) Get damn busy (study, work, volunteer work)
2) Tons of sweat (exercise!!!!!)
3) Buddy seems so so so much precious especially this moment.
4) Diversion (once I told everyone I like a new gal - I actually
dun know her at all. All my friend try to hook us up, the process
was fun. We ended up as friend though, for there was really no
action on my part)
5) KFC!!! I like oily stuff, especially KFC at times of stress.....
See me eat KFC alone.... don't come near me!
