Hi
@spage It sounds like you haven't been diagnosed long ?
I've been diagnosed almost 8 years now and have never required assistance with a bad hypo, however those around me know what to do if it happened, so firstly they would rub glucogel into my gums if non responsive, then glucagon pen as well as a 999 call. It's best that those around you are aware of what to do, it may never happen, but it's best that they are aware. Very often the liver will dispense glucose into your system too, hence why after a hypo you will very often go high, but best to treat this with caution as your liver will need to re-stock glucose again at some point taking it from your blood and can cause a further drop later on.
Maintaining good hypo awareness is important, you will feel a bit shaky/palpitations around low 4's at this point test and if going low below 4 then treat with 3 glucotabs, wait 10 minutes test again if still low then treat again with glucotabs and repeat until above 4, it's advised to eat a 10g carb snack. Are you aware of DVLA guidelines in regards to driving (if you do drive !) ? Always carry glucose in any form with you though where ever you go including at the side of your bed too, it's important when using insulin to make sure you can treat whenever/where ever you are.
Hypers need to be treated with correction doses of novorapid, but you need to speak to your DSN to work out what your correction dose should be.
A good book to help you along is 'think like a pancreas' written by a type 1, a good read to help build your knowledge. The NHS courses are useful but try and learn as much as you can prior to these as it will help you in the short term.
