I am type II, I could not tolerate the Metformin because of Gastroparesis issues, so I manage with Insulin (Lantus 20u a day) Diet and excercise are the other thing I manage it with - I was getting to the gym 3 - 5 times a week before Motor Neuropathy made working out, hell just standing, to painful. I am getting an AFO soon to help with that and hopefully will be back in the gym or in a pool.

Aside from the Insulin, I take a daily multivitamin, B12, B6, ALA, Gabapentin 3600mg/day, and Cymbalta 90 mg/day, also a small aspirin. Occasionally Ibuprophen if muscle pain from strained muscles is to much to deal with.
I take Omerazole and Domperidone for the Gastroparesis.

It was funny, I was sitting with the older folks at a church potluck and they were all comparing how many pills they take a day, the most they could come up with was 17. I probably take double that amount.

For all the listed side effects of "May cause drowsiness" it never seems to happen at night when I want it too. Maybe I should try some melatonin.
