Each time, I'm driving at least 80 kilometre per hour . It's always in the morning. And it starts with my feeling a little dizzy, then my vision starts narrowing, my hands start feeling cold and clammy, and I start feeling extremely disoriented. Each and every time, I've managed to get my car off the road, fortunately, and it takes me several minutes to clear my head enough to drive again. I'm 42 years old and taking diabetes medicine -glucovance 5mg one in morning and another in evening. I've also been getting dizzy spells when I'm standing and talking to someone, usually when I'm trying to focus on their face while they're talking. When these "spells" occur, it feels like my brain is a snow globe that's just been shaken. Did my blood test - everything seems alright except for glucose was 10.9 and cholestrol was 5.7 instead of 5.2. While my average pressure is around 90/130. Really need help to overcome this problem.
