I just say I decided to get healthy started eating right and working out. What I do at social functions is buy a drink ( ginger ale, wine, or grab a friend's empty beer bottle). This avoids all the do u need another one, can I get u a drink, etc... I just look at the drink and say I'm good. I did go through the are you sick ???? I love the ones that don't ask me and ask my husband if I'm okay. But look at it this way A. You must look great for so many people to make commitments B. Are you lucky so many people care about you to even notice C. After a little while the comments will stop because the new you has been seen by most people........Enjoy the compliments you worked hard for them.
