Testing Routines

I know this can sometimes be an individual thing & i know about testing when we are ill or after / before excersise etc but do you have a testing routine ie
1. certain days / times when you test before meals
2. certain days / times when you test after meals
3. certain days / times inbetween meals, also do you test 1 hour or 2 hours inbetween meals?
