I too am bipolar (II) and would never mess around with my meds, even to look great. Fortunately, even though some of my medications DO slow down metabolism, it was my psychiatrist that suggested the low carb diet as the most effective in beating the low metab drugs. It seems to be working. I take Effexor, Topomax, Zyprexa and Rivotril. How's that for a cocktail???
But the stuff works and other than the occasional depression I'm pretty even. But as stated in a previous post...bipolarity is a chemical imbalance - if you can get the right balance it shouldn't be messed with. Even the shrinks aren't sure what they're doing to get patients on the right road, most of it is trial and error. At least it was with me.
Cheers to all,
Finn
