Hello BipolarMama31: I'm sorry you're having this difficulty.

I'm afraid this is all something I don't really know anything about.

If you're this nauseous from your med's, I would think it would be important to discuss this with your prescribing physician. Perhaps a med change is in order. Or perhaps a consult with a nutritionist would be beneficial.
As I'm sure you realize, one cannot live on oatmeal & smoothies alone.

One of the questions that needs to be addressed here, I would think, is: is this really a side effect of the medications you're taking or are you possibly developing an eating disorder? Either way, it seems to me, professional intervention is the way to go. I offer you my best wishes with the hope that soon all will be well...
