Did your Endocrinologist tell you your medication isn't working? If it isn't then they would change the dosage knowing how imperative it is to have your thyroid functioning at 100%. I have hypothyroidism, and if you think weight gain is a big problem with this, it's not. You may gain up to 10 pounds and that's it. Don't expect that losing weight is a sign that your medication is working, because this won't happen. Only blood work can tell the doctor if it's working. I would check the Alli for side effects where your stool is concerned, and be aware that Alli is very bad for your liver.
I agree with Mammo 100 percent. I might add that, Charla, if you want to lose weight, the best way is to increase activity level to where you break a sweat every day, increase protein intake, reduce carbs, and drink lots of water before you meals, and no snacks, no sodas, no deserts. Make a graph chart, so you can plot your weight loss, and when you reach a goal, treat yourself to a new blouse or shoes. Those diet supplements do not work.
