I would like to know what drugs you are taking?

Your doctors may not think they are contributing but most doctors do not know how RX drugs deplete the body of nutrients which may be contributing to much discomfort.

For example, if you are low in B12 you may have terrible sleep disruption, because methyl B12 --the active form your body uses--is responsible for the synthesis of melatonin which is the sleep hormone. In addition there are new studies showing melatonin receptors in the pancreas may not work properly and contribute to Type II diabetes. Melatonin is also showing up as
blocking NMDA receptors which are activated by calcium, and low melatonin therefore may therefore increase pain levels.

So just being low in B12 (or using a drug that depletes it further) may disrupt alot of other systems in the body.

If you prefer privacy you can PM (private message) your drug list, and I'll check the reference I use.

Many things can happen with drugs... never underestimate them!
