Since the middle of October I've had a constant irritated throat, been feeling quite tired the last couple of weeks and I've just got my third cold in 5 weeks. I don't normally feel like this in winter, so just wondered if anyone has any advice for feeling better/preventation. I get around 8.5 hours sleep and have veggies/salad with lunch/tea and 1/2 portions fruit a day, so shouldn't be lacking vitamin C.
