This might be an odd suggestion but I suggest you watch a documentary called "The widow Maker". It's available on Netflix. With your history of familial high cholesterol and your desire to reduce carbs, it might be a scare tactic that could work for you. I recommend everyone watch this documentary but I feel it could really help light a fire for you. I'm sorry you have high cholesterol. The meds we take are often not good for cholesterol so you got a raw deal having bipolar and these issues. I hope you find something which works for you.
