Mastisol is an adhesive dressing- like IV Prep or the like. It's very strong and I'm willing to bet that using that alone will solve your problem.
I do use the inserters; I have found them to just take the whole "am I doing it right" question out of the process. Scary, yes, but well worth it. I always use my "be brave" concept if I need it: think about all those people who have survived stabbings! This little needle can't really hurt me...
I generally change my site every 3 days with the silhouettes.
When I first started on the pump in 1995 I used the bent needle. I was in pain every day. The people "most knowledgeable" where I was at insisted I keep using the bent needle for 3 months before I could use something else. Insane.
I eat everything and anything, pretty much. My A1cs have been 6.9-7.3 for the past 8 years, so I figure I'm doing okay. The docs want me below 7.1 but I tell them 7.3 is the best they're going to get with me in law school, working 2 jobs, and dealing with 28 year old hormones.
They've backed off a little, but still want to tell me to get below 7.1. Again, completely insane.
I'm re-reading your post and I just get chills when you talk about the steel needle. OUCH. The bottle of Mastisol I bought about 10 months ago is still about 90% full. I think it was about $25. I cannot encourage you enough to try that first! Use it after alcohol and before insertion and/or tape. If your issues are based on the sites falling out, Mastisol will most likely solve your problem.
Is it possible you've got scar tissue that is fighting with your insertion sites? Have you noticed the issues only when you're using certain areas of your body? I have been having to be a little more inventive than usual and travel outside my comfort zone. So far, it has worked well!! I only poked in, out, and through my thumb once!!!
THAT was funny, and weird.
I was diagnosed in 1988 when I was almost 11. Sounds like we have a lot in common!!
