Hey Cricket,
Sorry I didn't get back to you last night. I had a rough go with my MS and spent the whole night with my friend the porcelain

I found the bit in my book about pregnancy congestion. It says just steam inhalations. So basically boil some water on the stove, once it's boiling take it off the heat and then breath in the steam (be careful not to burn yourself). It should help loosen all the stuff in your nose and make it easier to get it out.
