"i am only on day 5 of the medicine. i had a headache on the 2nd and 3rd day, but i think this is because of no sugar. i have cut my carbs down alot and will weigh in on day 7. this pill has really helped me not want my sweets or even bread. i have made very good decisions and even plan what i&#039;m going to eat when out. i can&#039;t wait until month 1 to see my progress."
