"i have been on this for about a month, i was 345 lbs when i started and got as low as 317lbs. i have had headaches, no nausea, but i do feel tired all the time but i also have seasonal effective disorder which may play into it. i cheated a little by upping my dose every 5 days instead of every 7 but now i&#039;ve hit a plateau. i&#039;m hoping that i start losing again cuz so far this is the first time i&#039;ve been able to lose weight. this is my last hope. i haven&#039;t done any exercising because i&#039;m disabled &amp; its tough for me. i&#039;m hoping i can start once i lose more weight. it caused constipation &amp; diarrhea at times, i have gotten abdominal cramps if i try to eat to big of a portion or eat too frequently. i have noticed that i eat a lot less."
