If you use an amplification system for any CGMS or pump alarms, could you post here what all of the parts of your amplification system are, and how much it cost to start using it, and how much the continuing costs (of say, batteries) are? I've been putting off getting something to amplify my Dexcom because of cost and because of not wanting to lose sleep but for the last few months, I have one night every one to two weeks where I wake up really high, ketotic, an nauseas, having slept through hours of alarms. I'd like to put a stop to them. But I really don't want to spend a lot of money. So I went into radio shack today, to buy a mini amplifier, but it looked like the ones they've got, I'd need to also use a mic with or something, and when I told the clerk what I wanted to do, he said it was impossible.
