I have given up most dairy in a bid to relieve constantly blocked sinuses, and it seems to have worked. I'm now going to try the same for my son. Which milk alternatives can you recommend? We've tried Alpro soya unsweetened and he hated it - can't say I blame him. He mainly uses milk on cereals. I know it's down to personal taste, but I'd like some guidance before I try every brand on the market. Thank you.
