Hello @Vwvonnie Taking insulin shouldn't make you feel sick, unless it's injecting which I understand you're fairly new to, which is making you feel unwell.
Only a few days on it one reading is down to 13 then shoots up to 28-30 after iv eaten just trying to juggle it as I work nights and only really eat once a day
some people can't tolerate artificial insulin , ie , human and analogue , if you go on the IDDT website there is information there , there is an alternative of pork insulin which I am on but you may have to fight to get on it with your healthcare people telling you its not available any more and other rubbish - crazy really as its cheaper than the artificial
