Hi Brandi,
Just keep doing what you are doing!
I am on many medications, some of which, will most likely be discontinued as I go along on MF, others will have dosages decreased.
My first week on MF, I lost 10 lbs. Then, like you, the second week, I did not see a loss, until the very end of the week, and another pound was gone forever. I have lost another lb this week, thus far, also.
Everyone loses at a different rate, but on MF, you are sure to lose weight, however fast or slow that may be. Bottom line is: this program works, and if my medications are slowing me down, that is fine, because, I know that if I have patience, determination and the absolutely wonderful people on this site, encouraging me, I cannot lose anything but the unhealthy pounds! Good luck and keep going!!!
