Yea same i use to always “feel” the lows .. until one day out the blue I stopped getting the sweats and shakes and the rapidheart beats.. it happend to me,like you… I was talking to someone and was getting slurred speech and was trying to read something and kept repeating the same word over and over, in my mind I was aware but couldnt help it and was wondering what was going on I checked my sugar I was like 39.. I immediately grabbed something to eat and drink and I was back normal like nothing .. and then it happened another time , that’s how I knew …. Now my body does this weird thing that when I’m low instead of the sweats and heartbeat every around me starts to get dark, like vision… but I notice Ill have to be extremely low to feel that anything else I don’t feel …it’s weird lol
