"i have been on the med for one full week. my doc prescribed me 50mg 2 x&#039;s daily.  i immediately noticed a moderate fatigue. but it has been better toward the end of the week. my mind is a bit cloudy but it too is also a bit better by the end of the week. on the positive i have had no tingling in my fingers and toes like many reviews i have read. carbonated drinks taste terrible. i was a diet pepsi ahololic , and should stop drinking it anyway. and without out any other dietary changes i went from 210 to 206 this week! so, now i am going to eat healthier this week and see what happens.  rating a 9 only because of the fatigue.  good luck in your journey!"
