I found this site by googling "diabetes and mood swings. I have a terrific marriage with a wonderful beautiful wife. I made an adjustment with my insulin based on Dr advice and I didnt know that being na bit too low could produce these swings. In about 15 days, the swings murdered my relationship. My wife loves me to death and I her, but it has actually scared her. In fact , she moved out due to this. I am trying to print the members comments on their mood swings etc, but havent been able to, so I can at least show her that I am not a meanie, but it could be low sugar related. I can see "printer version" but that would only allow printing of first page even though I selected "all" when prompted by printer. Sadly, I was told to keep my numbers down, I did fairly well staying in the 90- to about 130 range.  A doctor, noy my regular one, told me to stay under 100. So, I adjusted my insulin. I didn;t know about the probs with low sugar. I must have been in a low enuff range to make a problem but not low enough to pass out. i was taking my sugars and was below 80 often...I really need help to try and salvage my marriage...I am very very down in the dumps, benjamin D.
