Oh good grief! She is so clueless. Sigh. Tell her you can't just hang in there. You shouldn't be hungry. Read the forum and you'll see that when the dose is right there is no hunger. You can't calibrate it to your weight. Oy vey.
If she won't tell you the dose, then you have no choice but to try Margie's suggestion. Skip tomorrow and see if you are less hungry. It will be at least afternoon before you feel any differently. If you are feeling better as the day goes on then the dose is too high. If you are feeling more hungry, then it's too low.
