"i&#039;ve had an excellent experience on this medication. i have ben on the medication and it is now close to the time where i need to wean off.  i have had side effects from this medication, though they were short lived and tolerable. during the 1st 6 weeks (+/- a week), i experienced nausea, head aches, borborygmus (or a loud active sounding intestinal tract). i did not have any vomiting or diarrhea ever. i did occasionally experience constipation which was alleviated by taking colace (1-2 pills 1-2 times daily as needed).  i began this journey almost a year ago to the date. i started out at 166 lbs (5&#039;4) and moderately overweight. i am now healthier and happier. i currently weight 138 lbs and have a target weight of 135 lbs.  very successful."
