The pump has it's upsides & downsides. The pump stays in my pocket and isn't much of a problem when I climb. The infusion sets, however, don't have an adhesive that's sweat/rub-proof (they are good at water, as I swim all the time with them) which is my problem (hairy, part-Italian that I am). There's only 3 places to put them, abdomen, thighs and butt. Amazingly, the butt one rarely has a problem, it's usually the lower abdomen/thigh, where my saddle seems to rub most. Additionally, I have no desire to go back to injections 4-6x a day, as the insulin types my endos keep pushing me on don't really support the odder than normal lifestyle choices I've made. Hoping to get out of this area sooner rather than later so I can find better medical professionals to assist with my pancreatic curse.
