Many thanks to all who have contributed to this thread, especially AndyS and Snodger. From these and other conversations, especially with my wonderful diabetic nurse (who has a deeper understanding of diabetes than all the ‘experts’ at the diabetes clinic) it seems clear that is not uncommon for people to have bad after-effects from hypos for up to 24 hours. As you’d expect, after-effects vary in individuals (ranging through splitting headaches, feeling severely hung-over, being sick, feeling very weak, etc). Having recurrences of these symptoms for several days afterwards but without further hypos and with normal BG readings seems to be less common, but effects seem to be alleviated by reducing dosage and letting BG readings rise to 8s and 9s (and in the end this will also enhance hypo awareness anyway, and thus help to stop the whole process getting started). This will all seem very obvious to you diabetes veterans out there, but I do wish hypo after-effects were at least mentioned in books on diabetes. I will try to persuade diabetes.uk to insert a sentence or two on their website.
As for me, having stupidly congratulated myself on this thread for having mastered my latest hypo, all hell broke loose over the next few days. Constant attacks of severe weakness, dizziness, gasping for breath, couldn’t manage a flight of stairs– I’m (slim!) 48 but felt like 88. Halving the medication seems to have helped, though difficult not to freak out at getting 9s and 10s at first. I still take a positive view of it all – I’m getting a very brief glimpse of how life is for someone with clinical depression, or an OAP with emphysema, but I then have the incredible luxury of switching back to a normal(ish) life. In a way that’s a privilege. But god I do miss chocolate....
