I have been using the CGM with the Revel for 2 months, before that I used the Paradigm CGM. I have worn sensors everywhere! My arms, legs, abdomen, and low back/hip. I found I didn't like it much on my legs, but I guess because womens clothes are snugger I felt like I always had something in my pants :/ I use the IV3000 that came with my kit, I have to use 2 pieces or else it starts curling up, I just line them up next to each other. It works great for me, I know a lot of people like the opsite flex fix but I have never tried it.
I don't feel like I need to "wet" the sensor with the revel as much as I did when I used the paradigm. I usually disconnect from my old sensor, charge it and while it's charging I insert a new sensor. That usually gives me enough time for any bleeding to subside. Luckily I haven't hit a serious bleeder! You're not supposed to start up a sensor if it's in that condition, I guess it messes with the data, it wants interstitial fluid not blood.
At first, I had no glucose alerts at all. I hate all the beeping this pump does. But after a few weeks when I got a better handle on my BG I have turned them on and adjusted them. I have a more generous range during the day, and tighter at night. 75-180 during the day and 65-140 at night. That helps me catch my BG if it's going higher due to DP. I used to set my low threshold to 80, but I found it beeped at me too much. I have actually reversed some of my hypo unawareness so I don't worry about the current low threshold.
I have never used the predictive alerts, I hate beeping and I would rather not be stressed out if my BG jumps from 100 to 120 for example, you will get arrows if you have a rate of change >10 mg/dl I think. As far as if I do go over my threshold, I set the reminder alarm for 2 hours high BG and 1 hour low BG, that gives me enough time usually to make a difference to bring it back into target.
I calibrate 4 times a day, and on the first day or two I try to vary the numbers a little. Suprisingly MM CGM works exellent for me between days 3 and 6 (I always restart at least once, and did it by accident 3 times, it still worked!) I don't eat much during the day and I think that is what helps it's accuracy. On my wild BG days, it can really get thrown off, especially if it's a new sensor. If you don't mind waking up in the middle of the night to do a random midnight BG check, I would start a sensor in the evening, like 5 or 6 pm, then you will get your first calibration at 7 or 8 - when you first start the sensor you have to calibrate again within the next 6 hours then it's required at minimum every 12 hours.
This is a complete science experiment! Once you get hooked up, all of these nuances will make more sense. I found it was a lot easier to get started with the Revel than the Paradigm but maybe it's because I already had experience. Good luck!
