I have a lot of those symptoms. I can go a week without wanting to eat anything, but I typically make myself eat. Then I get nauseous to the point I need to lie down. However, I have not vomited with it yet. I also have noticed that at least twice a week, I will bolus the appropriate amount for my food and then bottom completely out within 20 minutes of eating. Of course, my blood sugar skyrockets hours later. I have made a point to track foods and it is has nothing to do with any particular foods. I have brought this up to my endo but he says he doesn't think that is what it is because it doesn't happen constantly. Sometimes, I feel like I am talking to a wall with doctors. My gynocologist has diagnosed me with a neurogenic bladder but again my endo states that if it was neurogenic that I would be having really bad peripheral neuropathy, etc. Apparently, he doesn't think autonomic can happen without peripheral. I have researched the internet and it says differently. I also have the heat intolerance but instead of not sweating I sweat enough for twenty people. Again, I am told.....aw, it could just be hormones. Grrrrr!!!
I am usually able to tell if my sugar is low but sometimes I can be walking around doing normal things and my blood sugar will be 28-34. Then it can be 68 and it feels like it is 0. About a month ago, my sugar dropped to 50 and I was eating graham crakers and peanut butter. My 11 year old daughter (who has never seen me in an unconscious state before) called for me to come to her room to help her with a school report. The next thing I know, my husband (who is a fireman and an emt) was asking me if I knew his name. Apparently, I fell over in her room and was very unresponsive and then combative. Unfortunately, I did not have any glucagon shots and he had to put jelly under my tongue, etc. Also, I apparently, spit more out than got in because I was covered in it. It did the trick though. My mother always used jelly/sugar when I was unconscious as a teenager. At that time, we had no access to glucagon shots. Anyway, it scared my poor daughter to death, but now she realizes that it is indeed important when my sugar is low and not just a way to get the last bit of sweets in the house.

I do get tingly, pins and needles feelings in my back area that range from my neck to shoulder blades and into the backs of my arms. I didn't know if this could be peripheral neuropathy or not. I always thought that it would happen in my feet first.
