I was on it for a month and I really didn't care for it. I had low-grade nausea for a long time, and it made me feel a bit fuzzy in the head.
It is also metabolized in the liver and my enzymes are already a bit too high, so that's ultimately why I quit using it.
As for eliminating cravings, I guess it sort of did, but I still craved.
My doc then put me on campral and gabapentin and these are working much better for me. I still have the occasional craving, but nothing like I had before.
Good luck!
