Just go without it and see how you are tomorrow. Just on the chance you did take it, taking another dose could send you into a bad hypo, so just skip it this time (won't be all that bad for just one time) and continue back as normal the next day. Hope this helped.
yeah that did help thank you, it's 4 am here in australia and i've just been waiting up wondering what to do. I did have a high carb meal for dinner but it's something i eat on a regular basis yet my sugar levels stayed at 10 since about 12 am.
