I don't think so love - sorry. I had a bad throat last week, and when I felt achey I took paracetamol. Just sipping water will soothe it a bit, but I think unless it gets really bad you should try to sit it out.
I got inhalation liquid from the Dr's (think the chemist do one) that helped with the bunged up nose.
Have to admit though - and not advising it - I had a stinker on Wk 1 and had a couple of lockets each day and still had 11.5lb loss.
I also used a saline spray to clear my nose, as baby and I had it at the same time and got it for her
