Hi lucy,
i have had a pump for 1 year now and i seem to have more control over my diabetes. The functions on a pump are great. You can control what basal you use when you exercise. The pump i have comes with a wizard on the blood monitor where you can tell it how many carbs you are having and it will work out the insulin dose and deliver it so you dont need to get your pump out.
I usually keep mine in the pockets of trousers and the pumps come with a choice of tubing lengths so you can have whats comfortable for you. You can also wear your pump in your bra when you are wearing tight fitting clothes (this is where the wizard comes in handy) and the cannulas are hardly noticeable.
Hope this helps.
Josie
