Yes, go to WalMart. You can pick up some Novolin R for around $25 - $30 at WallyWorld. A couple years ago already, Walgreens price for Humulin R for $95... same size vial!
Be sure you tag or check in with Julie or Wendy before you start as we really like an experienced R used to be with you online the first few times. There are others around, too, who have used R but I just don't know their schedules.
Let's see if anyone on east coast time is available for Saturday morning (I've put out the word to see). If we do it Saturday with his pm shot, then I would probably not want to do it again on Sunday. Just depends on how he reacts to it. I wouldn't want to use it both Saturday pm cycle and again on Sunday am cycle. As Marje mentioned, it's not uncommon to see the next cycle be lower after using R. This is yet one more of those "play it by ear" scenarios.
I can work from home, so a weekday is fine too next week if that is better for my "coach".
Yes, I could do a 730p-1130p cycle next week, no problem. Closest vet would be closed at that time but a 24hr one is only about 15-20min away if things go bad. What is the worst-case scenario shooting 0.5 of R? I would have my hypo toolbox ready to go.
Numbers can drop really fast and by a lot. When we give R, the ideal is to see about a 100 mg/dL drop over four hours.
Some cats don't need that much R. It's better to start with 0.25 units and work your way up safely. If they drop hard and fast, you can set up a major bounce, and need to stay up late that night monitoring.
How do I properly measure 0.25u?
I have not seen any real sign of a predictable nadir time since Bronx remains just flat and high & has has no pattern. But since Lev normally nadirs later in the cycle with most cats, sounds like I should use R at around +1 or +2?
When numbers are high and flat, one can pretty much give R at any point during the cycle. I think that thought is probably behind Julie's suggestion to initially administer R in the latter half of the cycle ... well, that and having someone available to help when taking your AM shot time into consideration.
Yes, shooting R at amps, +1, or even +2 may work out well. Collecting R data will go along way in making these kinds of decisions. Also, Like Marje mentioned, once you see movement (being able to define onset, nadir, and duration) and depending on the onset, nadir, and duration of both the Lev and R... you may be able to shoot R twice in a cycle... once early in the cycle to help give the Lev a lower number to "grab onto" and once later in the cycle to either take the edge off a bounce or hold numbers flat going into the next shot time.
Yes, it looks scary, but also notice how she got to those kind of doses. It's a gradual process of working up to the right dose. All dosing is supported through data collection.
First time I used R with her I tested every hours for four hours and saw no change, went to bed with her in high numbers and woke up to green. 
Her R onset was late compared to most. It also meant I didn't like giving R later than +1 because the big R drop could coincide with her Lev onset where she sometimes did a big drop. I preferred giving R at preshots or before. ECID. I have a math background, and used to think of laying the L and R curves on top of each other, and trying to time things to avoid combined big drops.
Yes it was, sometimes I just felt I was hanging on by the seat of my pants .... but eventually it worked, and Crystal was pretty well regulated for her last few months. But I couldn't have done it on my own, my vet had never treated an acrocat and was horrified at the high dose; I took all my advice from the acro experts here, mainly Wendy, Julie and Suzanne, and others guided me on the use of R. So don't give up, you are in safe hands.
