hey! i dont think your goal is too drastic! I made goals for myself like that.I am 5'8..230lbs. I am hoping to lose 30 pounds by my birthday which is June 4..I turn 16!!!:):) anyway, then by the time school starts again, which is middle of August I am hoping to have another 20-25..then that would put me at, then another 25 by Christmas, which would put me at my goal weight of 150! do you think mine sounds realistic? I hope you achieve your goals and good luck! I have found it easier to even break down these goals into smaller incriments like by 10 pounds. It keeps me motivated. email me if you want.. ashley_gass@hotmail.com
