I have to agree JoannK, it can become 'itchy' at times, but I have found that it usually passes for me to be able to keep it in.
I just untaped my transmitter today after almost a full 7 days (2 restarts after day 3 and day 6) and waited the 2 hour startup, and just entered a new BG into the now re-taped sensor/transmitter. Hopefully, I will get another 2 days or more out of it!
In the past, I used to insert it at night and wear it all night and turn it on in the morning. After the last time I did that and had a TERRIBLE low (couldn't move, live along, got one glucose tab in mouth but couldn't chew....finally managed to roll out of bed and turn alarm off that had been blaring for 90 minutes...managed to find more glucose tabs below bed and FINALLY got some in my mouth...a BAD way to start the morning!)...I no longer go to bed with it off! If it is supposed to run out of 'juice' and turn off any time after 6pm...I turn it off beforehand and either restart it, or do the untape/recharge and restart it before going to bed!
The alarms go seem to get a bit louder at night...but they really don't. It's just the longer you don't respond to them, the more different things the alarm tries to do.........it will alarm a few times,. then it does thru a bunch of other tones, sirens, vibrations, etc. It is usually the vibrations that I feel and wake up enough to hear the alarms.
As I've said before, it has saved me from many a BAD bedtime low!
Well, it's now time to do that 2nd BG in the 1st 6 hours...and shortly I can eat dinner!
One other thing...ask your MD for prescription lotions to help with the itching....I don't have to use them very often, but my Rx for Desonide lotion has helped tremendously when I do have major itching issues from the tape and sensors!
