"i am sick today, no food intake, medication reaction to naltrexone to complete a contrave dose.  titrated up from 12.5 mg week one to 25 mg week two.  didn&#039;t notice much change but by day 2 at 25 mg, nausea started getting much worse.  couldn&#039;t eat a thing, couldn&#039;t even keep ginger ale down.  although i&#039;ve lost about 2.5 pounds the first week with very little exercise and a big cheat on easter, if this nausea and vomiting will be the norm, i&#039;ll have to pass on it.  not taking any tonight and will roll back dose to 12.5 mg tomorrow.  if i can tolerate that but see no more weight loss, i will chalk this one down to another plan that doesn&#039;t work for me.. at 56 years old i&#039;m getting so tired of this lifetime of trying to control my weight .."
