Reason for low.

This morning numbers were more or less the same as yesterday on waking and before breakfast, same timing, same dosage and breakfast, yesterday numbers stayed ok till dinnertime, today 3hrs since breakfast and they've dropped so have had to have glucose, no extra activity since breakfast, had a couple of mile walk yesterday after work would that make any difference. Cheers

It might have been the walk @Charl but it could equally be for no discernible reason. Type 1 does that a lot! Same meal, same starting sugar, same insulin, same routine - different result.
