On my way to a better me...

Since December I have lost 40 pounds. Its been working well... I am halfway to my goal of weighing 160 lbs. However recently I have ran into some hurdles but i am still on track, i just have to learn my weaknesses and make the right decisions when these weaknesses are challenged. My biggest challenge is my housemate, I honestly feel like he is trying to sabotage my weight loss. He harrases me for not wanting to drink beers or for not letting him serve me diner. And since christmas this houysehold has been a junk food free zone, and he has started bringing junk food back into the house... very unsupportive and very much against the pact we took after christmas. He is not doing so well with his dieting...
