I Have Excessive Phlegm - At Night (which Wakes Me

I have excessive phlegm - at night (which wakes me up) and my husband says I snore and make a gurgling sound. When I have breakfast in the morning, I choke up on phlegm. Not so bad during lunch or dinner. Some mornings, I have blood in the phlegm, and it seems to be getting worse. Also, I constantly feel fatigued. Is this an allergy?
