Bupropion / naltrexone
"I have been taking this medication for approximately l month  and have lost  23 pounds.  Have not had to take the tablet at night because I am not hungry.  I do have a little more energy but am having trouble with sleep.  It did cause me to have severe constipation.  My doctor told me to take pericolace. It is very expensive so I bought the cheaper equivalent.  I take one in the AM and 1 in the PM.  I take a bundle of medications which also cause constipation, tiredness, sleepiness, drowsiness.  So, I don't think the Contrave is  the problem, but it did add to it. I do forget to eat and am worried about getting enough protein. So, I bought ENSURE.  I seem to have more energy and forget to eat because I am not hungry."
