January last year a DSN suggested a pump to me as I'd been pulling out my hair for a long time trying to sort out my levels. No way, says I, for most of the reasons you mention. Yuk! Not a chance. By March I started to get more curious and watched lots of youtube videos made by diabetics using pumps and got more interested. Read up more on them and decided I wanted one; so next time I seen my consultant I was very keen to get put on the waiting list.
I'm now in my first week of using a pump, pesky tubes and all, and it is the BEST thing I have ever done. Wish I'd done it years ago now. Already there are big improvements in my levels and with a few tweaks they should get even better. I honestly don't find it a hassle at all, in any way. It makes life much easier. I'd completely recommend finding out more and asking about trying one out.
Just do it! Worst that can happen is you don't like it and just go back to pen injections again. Nothing ventured, nothing gained.
