Look in the diabetics section of the pharmacy. They have special sugar free versions of cold medicines, cough syrup and so on.

If you can't find it, ask the pharmacist. In some places they keep diabetic supplies behind the counter (heaven knows that's what will be shoplifted :eye roll: )

For stuffy noses breathing in steam can really help. Put some rosemary in the water, put a towl over your head like a tent and breath deep. I generaly just take suddafed for stuffy noses.

My cough recipe involves an onion and honey so that's out :/ Honey isn't good to take if your mucusy anyway. It's good for a sore throat without stuffy nose, but if your stuffy it can thicken mucus and make things more uncomfortable.
