It’s easy for me to say “don’t feel guilty.” But let me say it anyway. I hope people aren’t making you feel that way. There’s no law that says you have to explain to anyone why/how you’re losing weight. If you say “my appetite’s just changed lately,” that’s true. Why you’re taking the meds is nobody’s business. Also, I like to look at it this way–you’re finally getting something back from ADD, which may’ve taken a lot from you at times. And good job with the better nutrition. Keep doing that as best you can.
