Urgent help,please!

I'll try to be brief. Beforeevening meal tonight my reading was 4.8. Son bought us Chinese takeaway and I had shredded duck chow mein. Stupidly I forgot to have my insulin. Realised half hour later, so had my normal dose (I'm Type 2 and had 8 units of Novomix30). Hour later developed a corker of a headache and took a reading. BS was 16.9 and monitor was flashing "ketones". Came straight home and have checked ketones with Ketostix and it registered ++ 0.4 (moderate). On reading the leaflet it says in bold letters at this level I should phone docs. I don't wish to do this unnecessarily and have only had a trace of ketones before on diagnosis and I wasn't even sure as aType 2 I would ever have ketones probs. I'm assuming it's 'cause I was late having my insulin/combined with having higher carbs than i have been last few weeks.
I feel like packing into bed now, so do you think I will be okay to put off contacting the docs and just see how my BS are in morning? I hate phoning docs. unless really need to.

Thanks for the advice lionrampant. Much appreciated.

Ketones gone down to a trace this morning and BS 6.9, so all is well. Just SO relieved to lose that bloomin' headache.

iHs,
Thank you for that tip. I may well ask my DN about that. Don't often have Chinese food and was not expecting to last night but it was my son's treat and I tried to pick something off the menu without a sauce that was likely to have too much sugar. I'm finding takeaways are definitely not a good idea generally. You try and be polite and "fit in" and just ending up paying for it in the end.
