For me keeping my feet cool, helps (sleeping with one foot-leg out of the blankets seems to do the trick for me)..
At work I can't do that so I'm searching for some kind of cooling shoe inserts.
So summer months are the worst for me....Hot baths also
I tried all the RX stuff by the time it worked somewhat it made me dizzy..goofy so I quit it
I'm not diabetic but sugar/Chocolate seems to set it off also Alcohol...Dang! lol
I'm trying Metformin because it help regulate your glucose...The verdict is still out on this since I just started it..
