"i have been on this medicine for about 2 months. my side effects were headache, thirsty, tired and wired. felt kind of like i was stoned, constipation, insomnia. most of the side effects went away after i got to the full dosage. still a headache occasionally. and still feel wired sometimes. but i haven&#039;t lost any weight. i know it&#039;s a slow working pill but nothing. in 2 months. it has curbed my appetite and cravings. but no weight loss is frustrating."
