I think I might know the answer to this but in case there's anything I've missed.... I've got a really terrible cold. Been doing the usual sick day rules, checking ketones if BG too high etc. That's all going fine. But... my nose is so bunged up and my throat is really tickly and sore at same time. I know i cant take decongestant so I've been taking ibuprofen and paracetamol, drinking lots of water, hot water and lemon, using olbas oil and steam. But is there anything else I can do/use to alleviate my symptoms?
