If you feeling stable then why go back on it???You've lost weight, I'm sure your Liver is much happier. " Some" Pdocs wear blinders and they hyper focus on just keeping there patients in a okay place psych wise but they need to look at the bigger picture.
There are other meds that can be used on a PRN basis that are more weight friendly if you were to need something.
Sometimes we just have to verbally remind our Pdocs that meds that cause weight gain will effect our liver, kidneys... Lithium can trash a Thyroid etc etc etc and that needs to be kept in mind.
Be your own best advocate
