Mike’s blog is very analytical and in detail, it might answer some of your questions. Definitely worth a read, written well with some wry asides 😀. Read it here ]http://www.everydayupsanddowns.co.uk/2017/08/
Apart from Mike’s curious decision to aim for 50/50 TDD at the start of the trial (sorry Mike, but it was curious,I’d have thought a direct comparison with Novo doses would have been more appropriate but you did explain your reasons) his findings run more or less parallel with the other blog I read about Fiasp.
I am using Apidra which is marginally quicker than Novorapid, though not really that much, and it is fairly predictable for me. Though any high carb meal will see me rise quite high before coming down to a nice level hours later.. Use more to try to eliminate that spike and I will be hypo in 3 - 3.5 hours.
Last weekend we went to Bristol, mainly to visit Ikea for bits and bobs for the new house, but as a pleasant adjunct to the visit we were able to meet up with and share an evening meal with Mike. We had traipsed around Ikea most of the day and then returning to our hotel in the City Centre we’d gone out again shopping for shoes (for Julian not for me, before those comments about women and shoes!),returning to the hotel in time for a quick cuppa and change before meeting Mike at 7pm and another smart walk to the restaurant. We went to a tapas restaurant, so guessing carbs was a bit iffy... but when we both tested before dinner I was 3.6....obviously the exercise had dealt a little too effectively with the stodgy lunch of Swedish meat balls in gloppy over-thickened sauce as proffered by Ikea. My pump won’t allow me to dose if under 4, so I had to wait until into the meal to do it. For quite valid reasons which Mike will explain himself, he was a fair bit higher (9ish Mike?). Anyway after a pleasant evening of waving our pumps at each other, discussing their ins and outs and consuming some rather tasty morsels of indeterminate carbiness, accompanied by rather nice red wine, we both tested almost identically in the 11s. Leaving aside my later dosing, Mike had only risen by about 2mmol whereas I had shot up something like 8mmol, all too frequently the norm for me with higher carb meals.
Next morning- presumably due to the red wine and a nice Spanish brandy I was happy with my FBG of 5.5 and never went much above 6.8 all day.
