Im still honeymooning after 6.5 months and I do carb count but I've not given myself any carb to ratio doses. This is because at the moment I know i can eat roughly 100g carbs and take 2u of novorapid. This is only with meals I know my body can deal with. Pizza and co it's trial and error. Any bread bar burgen bread is off the menu as no matter how well I think I've cracked it, I get a late spike in blood sugar.
I've decreased my Lantus to just 2u from a huge 4u back in June as I was dipping into the hypo zone a lot.
You just have to test a lot before food and then 2 hours after. You will get an idea how your body deals with it so you can give yourself x amount of units to cope. Write everything down for future reference and that way you can tell if your body is not coping as well as it was a few weeks ago.
I have an active job, sun- thurs and I know I can keep levels at an ok level. Fri and Sat I eat more but take more insulin but I'm not as active and I see the differences in my readings.
It doesn't take long even during the honeymoon period to realise which foods spike you and which ones are fine. Christmas day I ate like a king, drank like one as well. My highest bs test was 8.9 mmol. On Boxing day I had a few chips and chicken sarnie ( white bun) and I was 12 mmol and this was 6 hours after eating.
I've took my insulin and felt nothing's happened at times, some pens were opened for 2-3 weeks but I changed them and things seemed to settle. Dodgy insulin? Or a sly custard cream? No one knows the real answer and as a t1 this is how it is.
Good luck, sorry if that doesn't make sense as I'm having a few drinks for new year as I'm at work new years day.
