You don't mention if you're on any medicine. If you're on any that might be lowering your BG levels, you should be testing, to help identify and avoid hypos.
More generally, this forum recommends that all T2s should test, but for a different reason. T2s need to know how what they eat affects their BG levels, with regard to pushing their sugar up. They can then avoid those foods, for better control.
GPs, DSNs etc tend to be against testing, because they think it will only make someone anxious. This may be true for some, but not for the kind of people who come to this forum for help. You'll find horror stories on here, but not from the people themselves, people who think 'doctor knows best'. Usually someone associated with them, wishing they'd take more resposibility for their condition.
