Dont worry about it I shouldnt think
Muscle twitching isnt necessarily a symptom of serious problem, esp in absence of other symptoms. Sometimes is just electrical impulses, though not sure of exact science However see Doc if you are worried - put your mind at rest
If you are not long diabetic (and isnt it a huge blow, and a PITA :? ) and you've split up with a girlfriend, its no wonder you are feeling rotten generally. Also, when you're health has been compromised, its only natural to start thinking you are vulnerable to lots of other things,especially when you have an autoimmune condition
What I would say though is you are doing well -great A1c. However, ifyou are having lows
check during the night and adjust your insulin/food if you are having lows.
