Here are my thoughts:

This is from a man who deals directly with Mania and have only had one episode of clinical depression after my original diagnosis.

My problems relate directly to blood sugar levels.

The riddle I had to solve myself is how to keep myself balanced and keep my mind from going into an upward spiral.

The key is diet. I find that leafy greens (primarily spinach) provides the nutrients and cleans the body of toxins as well as being a source of appetite fulfilling energy.

With the reduction of sugar/carbs in my diet I was able to reduce my dependancy on Zyprexa to shut down mania episodes. At this point I've been completely off meds for 6 weeks while relying completely on spinach as my main meal 2-3 times daily. Around 200 calories of spinach daily.

Starting the spinach diet also provided me the energy needed to workout. So between diet and excercise I have been able to lose 15-20 lbs in 5 weeks or on average 3 lbs a week steadily along with 2 belt notches.

So, do I believe that age matters? Yes.
The reason I believe that age matters? It takes longer to recover from injury and metabolic rates slow down. Therefore if the body/mind gets out of whack it takes longer to properly clean up. Thus, yes bipolar can get worse with age.

However, trends can be reversed applying the right pressures.
