I first heard about pumps about three years ago when I was going through a particularly bad time with hypos - that was before I changed over to Lantus and Humalog and things settled down a lot after that.
More recently though I made a major effort to lose weight, take up exercise and get better control, and the frequency (but not, thankfully, the severity) of hypos increased again.
I joined a couple of message boards where there were lots of pumpers, and this made me want to give it a try. My diabetes team were very supportive, they put me through DAFNE, encouraged me to try every available combination of analogue insulins (Levermir, Humalog, Novorapid, Apidra) and finally I got my pump in August this year.
I LOVE the fact that I can take precisely the dose of insulin I need for the food I want to eat, I don't have to round up or round down or eat extra.
I love the fact that I don't have to do anything except test when I get up in the morning and go to bed at night.
I love the fact that I don't have hypos every day any more: or even every week!
I love the fact that I don't have to do injections every time I eat, which even though I used to do through clothes, still led to the occasional embarrassing blood spot and therefore was not feasible when wearing light colours.
About the only things I don't like about it are the fact that changing the infusion site and insulin cartridge is such a polaver and has to be done at a certain time of day (so that I can test and make sure that the new site is effective) - typically for me that's tea time - the fact that changing clothes is a juggling act - the fact that Apidra in a pump, on me, lasts only 3 days before it loses its potency, so I have to change the cartridge every time I change the infusion site - but all of these are really minor compared with the above!
I don't wear mine in my bra. I tried it, and it really doesn't work for me (size 38A might have something to do with it!). I did once wear it in a pouch round my neck in order to wear a dress, but found it too heavy to be comfortable and very noticeable. I wear mine in my pocket, or if I don't have pockets, on my waistband. This means that I can't wear dresses - but this isn't something I do much anyway.
