Many years ago, I'd cut out caffeine and simple sugars completely. I had more energy, and lost a healthy amount of weight, and in a generally good state of mind. It did become easy to live without all of that stuff.

However, looking back, I see much of that time I was either hypomanic or towing the line---lots of the typical stuff. I did not get to the point where it severely affected my life. However, I was in my early twenties then, and my hormones have most likely changed since.

I'm all for cutting out caffeine (though I see no problem with some caffeine on occasion) and sugar--the simple sugars I'm trying to cut back heavily on, if not eliminate entirely. But with everything else I deal with currently, I can't focus on that as strongly as I'd like. Nor am I saying in any way not being on all of that caused my hypomania or that there is any correlation. I'm just saying at least in my experience--so far--it may ease some of the symptoms, but hasn't rid me of Bipolar entirely.

I will be looking into the article you posted, Genetic. I'm all for learning more about this.
