That handsome bastard.

Here are some links to diabetic diving info:

You should also subscribe to divemed and search the archives for
diabetes-related stuff. There's quite a bit.

I'm not a doctor, so I won't give you any advice. But here are some of
my considerations.

Nothing will bring on a hypo like the loss of body temp in the water.
The colder the water, the faster yer bg will drop. I always carry a tube
of gelled glucose (Insta-Glucose) in a pouch I made and attach to my BC.
I can get at it without removing it from the pouch or detaching it from
my gear, and can use it underwater. I carb up before diving with some
high glycemic index food about 45 minutes before diving (great excuse to
eat a sticky bun!) and a Coke and/or a banana between dives.

I don't advertise. Diabetes makes boat captains and divemasters do and
say all sorts of irrational things. My regular buddies know the routine,
or I dive solo. If I am in a situation where I must dive with a
stranger, I give a phony name and say nothing else.

I'm not sure what depth the pumps are rated for and I understand some
have dived with pumps. I'd be a little concerned about the infusion set
(snags and infection), but you need to find other pumpers to work that
out. I think there's been some pumper-diving stuff on scubadoc.

If you've only been on insulin for 12 years, you prolly still have
pretty good hypo awareness. They do seem to come on a bit quicker
underwater, but I think that's just because the earliest signs are not
as easily caught.

Long deco routines are a no-no. Feeling a hypo coming while ya still
have a 30 minute deco obligation is a real hand-wringer. Been there,
done that, no one sells the t-shirt.

And what's a BEVY?

If I were you, I would not be seeking advice of this newsgroup or any
other newsgroup or internet chat/info line for your question.  If
you're on an IP, you were probably brittle and you were probably
having problems with control.. otherwise you would still be on "the
needle".   Chances are that you still are brittle even while on the
pump.  You may not wish to acknowlege that and I'm sorry if I've hit a
'sore spot' with you.  I'm not trying to be harsh with you but I am
trying to point out that your life could depend upon the correct
information and all I am doing is trying to enforce the importance of
that into you because I wish you well !!!!!!!!!

Since no one here seems to know what you even mean by stating that you
are diving "in the BEVY this Feb",  I think that very tidbit should
clue you in even further to forget seeking advice on such a sensitive
issue from a newsgroup. LOL

IMHO, you need to be able to clarify your hourly basal rate now and
compare it to what you will do be doing activity-wise on the dive you
wish to do.  If you have a carb-count sliding scale that you add in
with meals or a few times a day in addition to your basal rate, then
you need to know how to factor that in while you are diving.  Your
life depends upons it !!  Please ask your endocrinologist..... who
should be the one who is governing your pump rate in the first place
!!!!  And lastly,  but not least importantly, you need to make sure
that your pump can withstand the pressure but on it by the dive.  Do
NOT take your doctor's word for this...  but rather call the
manufacturer.

Best wishes !!!!!!!!
