Well for me, i was thin all my life. i could always get away with eating anything and wouldnt gain an ounce.... i remember i never understood those people who said "oh my god i hate you! how do you do it" ... then i hit 25... i gained 15 lbs... and i thought "piece of cake,, i'll loose them in a jiffy!" yeah right.... 15 became 20, 20 became 25, 25 became 30... and now... 35 lbs later, i am now one of those people who look at those skinny chicks and say "Oh my god i hate you! how do you do it??!!"... it's been a humbling experience, i lost control... i let go of myself thinking i could always bounce back. fact is, the older you get the harder it is.. i took it for granted, now im fighting back because i miss myself, the way i feel, its all changed.
