Like you, I'm having to get used to the cost of test strips. I started using a meter at the beginning of August, doing pre and post-meal readings every day, i.e. 6 readings a day (my waking up reading is my pre-breakfast one). After a while, I started to see patterns and made changes, but also became aware of the cost. I'm someone on Pension Credit, and couldn't see me being able to keep this up for ever.
So then I did a week on and a week off, and that seemed effective. My diet changes were getting settled, as were my changes to how much exercise I was doing. I then had a break of a couple of weeks, while I spent a lot of time thinking about the pattern of results I was getting, and now I'm back to 6 readings a day for a couple of weeks because I want to monitor yet more changes I've made to my diet.
In all of this I've kept records of what I've been eating, regardless of whether I've been testing. Now I'm also adding in the exercise to the day's records. Overall, I've got 5 readings down, and my weight's started to come down without me doing anything particular about that. The low carb diet and more exercise seem to be doing that for me.
So, like me, you might end up not doing as many readings as you start off doing. There's a bit in David Cavan's book where he goes through various suggestions about how many tests to do and why, at different stages of developing your management of your diabetes, and there are some good comments here about that, too:
