Thank you @
eabhamurphy, what you've said is very reassuring, especially from someone so new to a pump - it must be a fantastic feeling to be so in control; and very interesting that you're now more concerned about having no insulin at all, rather than too much! Yes, I suppose keeping a close eye on it is key, as is having supplies and a backup pen.
I used to use the Libre, but now use the Dexcom G5 - I prefer it, as you can set an alarm to go off when your sugars reach a certain (user-defined) level. I got the Dexcom to warn me of sugars going low - but, if you're worried about a lack of insulin (i.e. while sleeping) the Dexcom would sound an alarm when your sugars reach a pre-defined high - which in turn could allow you to check that the pump is delivering insulin correctly - a bit more expensive, but worth a thought perhaps?
Your comments about the advantages of a pump echo those of many others who have kindly provided me with advice on this forum - I think my problem is over-thinking things (can't help it, it's just the way I've always been!) - and the question of "What if it malfunctions is some way" is the only barrier; however, as with most things in life, I suppose I'd feel differently once I actually try it.
Again, I'm sorry to hear of your traumatic hypo - can I ask, did that experience cause you to worry about actually injecting insulin at all? For me, my hypo made me paranoid about even small doses (like 2 or 3 units) - for example, I'd worry about the possibility that all the insulin would act immediately, rather than over a few hours (illogical I know - but couldn't help the constant feeling that I accidentally hit a vein or something); also, when sugars did go a little low, instead of thinking "Oh, no problem, I'll just have a little Lucozade" - I would instead think "That's it, I'm going to pass out and go into a coma - there's nothing I can do to stop it - I'd better text my family" (!) - strange I know, and irrational - how the mind works in mysterious ways!
