Hi Ally! I definitely would recommend a pump if your lifestyle is very active, hectic, and maybe unpredictable at times. I'd also recommend one if you're having a hard time controlling and managing your diabetes on injections. However, do keep in mind that being on a pump by no means allows you to eat whatever and disregard exercise. Please, join the group Insulin Pump Therapy for more insight.
I have good insurance, but what are other costs associated with a pump? If you get the CGM, most insurances will not fully pay for the supplies. Other than that, good insurances will pay for 80% of the pump itself and then usually cover 100% of the supplies.
Do you feel that you really do have better glucose control? Since I've been on the pump, I've never had an A1c higher than a 10, but I average about a 7 - 7.5.
How comfortable is it to sleep with a pump? I got used to it pretty fast. It is a bit bulky at first. I usually wear a loose tee to sleep in which I'll clip my pump to the end of it, so when I toss and turn, I can just shift the pump out of the way of whatever side I'm lying on.
Does a pump inhibit you in your daily life in any way? Not really. Sometimes, I'll forget I even have it on and then that's when I get careless and either bump it up against something or snag the tubing. I've only had the site been ripped out once, but it didn't hurt, just sucked. (You can always look into the OmniPod pump because it doesn't require any tubing.)
What about the infusion? The infusion is pretty comfortable...You don't even feel it.
What about the risk of infection? As long as you're cleaning the site location and washing your hands before injecting it and then changing it ever 3 days, it should be fine. I've cleaned with just soap and water (like after showering) or used rubbing alcohol to clean the area, either way, they both work fine. I've gone 4 days (5 days max one time) with the same site in a few times (not recommended though) and never have had an infection.
What about long-term usage? Not sure what you mean about this question, but I've been using the minimed paradigm pump since 2003. I started on the 511 model and then in 2007, I upgraded to the 522 model. There has been no known damage so far. Once, I got tired of using the pump and with an OK from my doctor, I went back to injections for a month...But, this required that I start back on a long-acting insulin along with the short-acting, since you only need a short-acting insulin when on the pump. It's pretty easy to go back to the pump, but you just have to make sure all of any long-acting insulin in your body is out of your system before putting the pump back on. (They explain that to you when you get your pump.)
How do you wear a pump when you exercise (if you sweat a lot)? For this, I have a cotton arm/leg band with a cotton pouch attached to it so I can slip the pump in it. It absorbs the moisture while wearing the pump, plus you don't need to find work out clothes with pockets.
I hope this helps some.
