Turning in 40 in 5 weeks... - NEED MOTIVATION

I am turning 40 in 5 weeks and I would love friend to help annoy, pester, and be a pain in the butt to keep pushing me..
I cant say I wanna lose the entire 20kgs, but at least 5... I know I can do it, but I drop off after a day or two...
I need people to keep me in check.. I would love some support xxooo
