What helped me the most was

1) going gluten free/dairy free and

2) taking a good non-dairy pro-biotic and NAC 600mg (N-acetyl cysteine).

I haven't had a sinus infection since 2008 and I rarely get sick with colds/flu and I no longer have allergies... I know this may seem extreme but it is worth it. Hope this offers some hope!

Good Luck ~ Carleen
