Ow Alice, take care of yourself

I heed your story very carefully. Thanks for the suggestions guys, I'm modifying as I go and trying to add in a little core strength training somewhere... I'll work it out.
Shiftzor, I''ll try after meal with the bolus down as you suggest, I've been burnt by repeated lows but I think part of the the key also lies in getting my basal right down as well in time. On the pump, my basal has a three-four hour lag, so I gotta get that happening sooner than I have been...
Happy to report that after just a few sessions of those stupidly low weight exercises, I feel my shoulder strengthening a little and my neck feel more limber in general. Now I just have to Keep. Not. Overdoing. It. I am thinking of tattoing that to my head

It is a shame I can't program my pump with a custom message to come up every few hours.
Just a question to the weight users, should the 3 exercises I am lightly doing for the arm give a general purpose strengthening for general use? Something else I should do as well or instead? Lifting things overhead is probably the worst for me... I don't know if that means I should do very light exercise overhead, or conversely avoid it.
