I had my training and start up of my new DexCom CGMS on Thursday. I had a shaky start, but am loving it now! It really is amazing to see just how well Symlin supresses my post-prandial spikes! I can also see that I need to play around more with my bolusing strategies. So far I have warded off 2-3 lows before they sunk, and have only caught 1 that the DexCom did not. The only times I've gone up out of range have been when I've eaten carbs and skipped Symlin. I guess those who are not on Symlin learn to pre-bolus 15-20 min prior to eating. I'll have to work all this out. Just having all this data is amazing.
It turns out that I'm (most likely...we'll see what happens when I start a new sensor) one of the "lucky" 10-15% of users who have some sort of reaction for the first 10-12 hours of a sensor. This means that my DexCom readings did not make ANY sense for the first 1/2 day; nor were they even close to the meter readings. They call this "noise". The guy from Abbot said that they found there's an immune reaction that can take up to 10 hours for people to overcome (that's why the Navigator has a 10 hour start up...). I guess when I go to start the next sesor, I'll insert it the night before I want it to go active. I can leave in the current sensor and then just switch the transmitter from the old to the new in the am. OR, since my nights seem to be pretty stable, I could just insert it and then start calibrations in the am and take out the old one. I'll just play this one on however my bsls seem to be going that night.
I have not experienced the "shower spikes" that many people complain about. The sesors are not water proof. They do make shower covers, but they're TegaDerm (sp??). I have not had good luck with that kind of adhesive in the past, so I chose to skip that. Instead, I just pop out the transmitter and carefully pat everything dry. So far, so good. We'll see what happens when I go swimming tomorrow.
Amazingly enough, I am doing fine with the tape- no itchy spots or irritation of any kind! It's been in since Thursday. If that was a pump site I'd be on Benedryl by now....
I do feel a bit funky having 2 medical devices taped to my body. Thankfully they're both discreet. Also, having to remember the receiver every time I move to another room is taking some getting used to. I have been putting it in a pocket for now, or in my purse when we're out. But, I can imagine that it'll be a bit cumbersome when jeans season hits. Any chance that shirts with pockets on the sides will be in style this year?!
My only disappointment so far is the meter. I really don't like the OneTouch Ultra. It takes WAY more blood than the BD one did (maybe that's why the BD one isn't known for its accuracy??). The case is a little small considering that the strip vials are HUGE. I'm guessing that the vials are the same size no matter how many strips are in them? I saw that you can get them in 25 or 50's. Also, the cord to plug the meter into the DexCom for calibration is 6' long. That's insane! Thankfully our trainer remembered how to do the old spiral shoelace trick and was able to wind the cords up for me. It still doesn't fit inside the case with the meter.
