I only used about 18-22 units of insulin per day, and i've been on the pump now for a year. of course as a newbie, i followed the directions to the letter. now that i'm a "seasoned pro", i've been filling up my insulin more and more to the point where i can go almost a whole week without having to change out my inset and fill up more insulin. it not only is less time consuming, but of course it's going to cut down on costs, especially now that my new insurance only pays for a cap of 50% and $2,000 per year for diabetic supplies.
so far i haven't had any issues with irritation or infection. just wondering if anyone else is doing this? what about reusing the infusion sets/cartridges? i know one of the cons that i've read is that having the insulin in the cartridge more than 2-3 days can make it go bad, but so far, i haven't noticed a problem.
