After work I checked my blood sugar and it was 399, I know this is bad is there anything I can do tonight until I can reach my dr. in the am

Exercise for at least 20 minutes. Rest. Check your sugar again. Exercise after a half hour if you need to. That was the only thing that worked for my uncle. (He'd ride his exercise bike.)
