Hey Kristoffer,
Insulin now comes in three forms - shots, inhaled and pills. From what I understand the inhaled version can mess with your lungs, so that's out for us. Due to our absorption issues, the pills aren't a good idea either - it'd be even harder to regulate, since we'd never know exactly how much of the insulin we're actually absorbing on any given day. So, from what I hear - shots wind up being the most accurate, and what they reccomend for cf-ers.
I'm no expert - my sugars are high, but in that questionable range - so I've only recently begun considering insulin and discussing options with the doc.
Good luck!
Kris
