I had high cholestrol 1 1/2 years back and now it is almost normal after taking a medicine (Simcar) for 2 months and then diet/exercise. However, occasionally when I drive car especially in the expressway my body feels different and I can feel blood flowing all over the body. I just feel so much uncomfortable and sometime feel like driving in an expressway for the first time. When I return home and check blood pressure at this time usually it is very high. I just get a feeling something is going to happen during the driving. I too drink lot of water during this time and wearing driving glass or sun glass makes me little better but not fully.
I checked with cardiologist few months back and he also did nuclear stress test and told I am fine. When I told about my shaking conditions, he told me to park the car and calm down. I am not convinced with my doctor's advice whenever I face the above mentioned problem.
