Whatever, your type, I think it's important to test whenever you feel you need to, always supposing you can persuade your surgerey to give you the strips. I'm getting them at last, after having the emergency services called out to me twice in a month the surgery got the message and are letting me have 'up to' 100 per month. It makes a huge difference to me as I was having to buy mine and therefore scared to use 'too many'. My Excel chart has gone a long way to towards convincing the power that be as well. It clearly shows the roller coaster I've been on and is actually proving a very useful tool to see what's going on in between HbA1cs.
