Has anyone ever taken phentermine while breastfeeding? My doctor prescribed it to me. I have an almost 2 year old who I'm trying to wean. I only breastfeed at night time while putting him to sleep.

I know it probably isn't recommended so I haven't started taking the pills yet as I am doing research. But just wondering if anyone has done this. Are there side effects? I'm probably going to stop breastfeeding before I stop the pills. But just curious.
