Need to?... possibly not.. should you ? well if you want to know which foods to eat and which foods to avoid when trying to avoid elevated blood sugars then yes a meter is your best friend. Most of us a regular testers especially in the early days post diagnosis so I woudl certainly recommend getting one. It's fairly unlikely that you will be prescribed one so if you want to self fund there are two with reasonably priced test strips (which is the major cost factor).
This is a response from an earlier post

(or telephone: 01923 711511)
for the SD Codefree meter, which costs £12.98 or:

(or telephone: 0116 2865000)
who distribute the TEE 2 meter, which is free.
The cost of testing comes down to the ongoing charges for test strips and lancets.
For the SD Codefree, the strips are £7.69 for a pack of 50 and there are discount codes available for bulk purchases:
5 packs x 50 use code: 264086 .. cost is £29.49
10 packs x 50 use code: 975833 .. cost is £58.98
For the TEE 2, the strips are £7.75 for a pack of 50 .. but there are no discount codes currently available
Make sure that you tick the appropriate box on the on-line order form and you won't pay VAT on your meter or strips. For the bulk discount on strips for the SD Codefree, you need to complete the order (check the boxes to confirm that you are diabetic and the number of packs that you want). Then click on view basket and on the left hand side of the window you will see two boxes .. Coupon Code and Apply Coupon. Enter the relevant discount code in the first box and then click the Apply Coupon box. This applies the discount and adjusts the price .. and finally, you then proceed to checkout.
I should add many thanks to
