I always test if feeling differently, the results either confirm that I am low or even going high, my symptoms for highs and lows are different. The meter is proof that ones feeling are correct or wrong, if I treated a suspected low but the feelings were to do with something else, I could go high if I was in the normal range, especially as at one point as I was getting false hypos (as sugar levels were way high).
As for meters these are not normally a problem in getting one free, by ringing the suppliers and answering a few questions they generally send you one free. The likes of Bayer, Abbott Medisense, Accu Chek, life scan have all been good in providing meters have a look on their web sites to see which meter you like, some they hold for people on insulin though would offer an alternative.
Strips is down to the post code lottery and your practice, and you may need to justify why you want them on prescription, some will and some won't give you them on prescription.
If you want to self test and have to fund the cost of the strips Abbott sell the strips direct to you a lot less than you can by them over the counter. The cheap strip option is the SD code free system (on amazon), also is the supercheck2 system, but go direct to them as some sellers sell the supercheck strips at a lot higher price.
I have bought a couple of meters and a good value ones are the Accu Chek mobile at just over £18 on Amazon and mine came with a 50 strip cartridge, though you will need to get more lancet cartridges. The Bayer Contour next usb came with 25 test strips, I had both of these sent free, though did buy a spare accu chek from amazon, these 2 meter are my favourites for different reasons and both suppliers have excellent c/s.
