Lprd since more than a month (2) Dinner?

I was diagnosed with Laryngopharyngeal Reflux and granular pharyngitis in feb last week and was asked by my ent specialist to take Neksium for a month. Now I met him again n he said that the dilated vessels have reduced near the vocal cord a lot and it's almost negligible and also the granules on the pharynx has also reduced much and there's only a big granule with some dilated vessel now. But I still have that heaviness in my throat general in evening or after I take food and post nasal drip. At times I feel pain in different sections of neck. And I've been asked to continue neksium for 10 more days. Kindly tell me that, 1. Hw long does it take to resolve? 2. Is there anything to worry about because I was a smoker before but I've stopped just in January mid. Can it be due to withdrawal too? 3. I also used to take Raw Indian Gooseberry 3 per day with breakfast frm Nov to Jan can it be a reason? 4. Any home remedy or ayurvedic med. apart frm non spicy food n sleeping 3 hour aftr dinner?
