Congrats, Earl! That is great and I'm happy for you.
I agree with your mom as well as others. You may want to mention it to the drs. A quick drop in weight for no reason warrants some attention; general rule - a 5% drop/increase or more. Did you change medications? I put on 30 pounds by starting all these meds. Once I stopped taking Paxil I lost 20 within a month. Just an idea.
Enjoy the new you!
