What have you already done?
I've just looked back through your posting history and you haven't really told us anything about yourself.
You just seem to pop up every 4 weeks or so with a similar question, and no feedback about what you did and if it fixed the problem.
So - are you on insulin?
If so, what regime?
When did you test - before or after a meal?
What have you been eating?
What other medications are you on?
The answer to "what should I do" is "give us some information to work on".
