Belfie, poor you! I feel for you I really do. That dreaded flu I picked up at the hospital visits wrecked havoc over my entire family and I was the only one not able to take anything. I was told in the past that nasal sprays are okay to use but I'm always sceptical too. My understanding is that nasal sprays are safe while breastfeeding. If you're uncertain ask another chemist or google the company that makes sudafed for more info. Ummm, I think.... mothersafe might have some info too, worth a shot perhaps.
