Last year, my nose was going bananas as our tree got a bit older. It took ages to work out what was causing it, but it was honestly miserable. I had to hide upstairs and make DH take it away! My nose recovered shortly after, but since then any cut flowers or anything will set me off.
I do have allergies anyway, but this was the beginning of me getting them indoors and certainly the first time I'd had it in the depths of winter 
Do I need to get a fake tree? Or has anyone found a tree which doesn't cause this, having been allergic before?
