health problem 3+ years please help

hi everyone,

i have horrible mucus or stomach acid every day. generally not much or none at all at first, but soon as I eat any food or drink, it flares up. I cough it up, its also in my nose. Feels like a wet cough, but I don't believe its in my lungs. i do smoke 4-6 cigarettes/day, but my doctor said my lungs are fine. the mucus/acid is usually clear I've seen many ENTs, they don't know what it is. I even got NAET treatments, but nothing. I thought it was allergy based, but now I am suspicious it is acid reflux. I've tried so many things- candida diet (thought it could be that), nettipot, bromelain, various other natural remedies. I do find some relief from kombucha- which makes me think this could be stomach acid related.

A few things about me:
23 yr old male
I make juice every morning from some or all of the following: carrots, oranges, asparagus, kale, ginger, lemon, celery.
I drink coffee (1-2 cups per day) and am often a slow sipper, constantly working on a cup throughout the day. Drink with almond milk.
Drink 1-2 beers every night or every other night
I tried cutting dairy and sugar to see if symptoms would clear. Can't really tell if its helped or not.
exercise 3-4 times per week


Any solutions? Anyone experienced this? It's very unpleasant, and I feel stuck. Especially since I'm still pretty young, and feel so crummy. I'm anti-pharmacuedicals because of many bad experiences in the past, and also because I feel Western medicine often doesn't actually cure the underlying causes, just alleviates the symptoms.

Thank you for your help- I really hope you can help me find a solution!
