I was prescribed adipex when my weight reached 210 lbs after having a kid. I was on them for 8 years, more time being on them than off of them, got down to 155 lbs while being 5 ft 8 in. I slowly lost the weight but I felt great and was happy with myself. Haven't been on it for over a year now and my weight is back up so if I even tried to get back on them would they even work the same? Would there be any long term problems after taking them for as long as I have? The longest so far I have seen anybody talk about was 5 years so I was curious.
