Hyper Acidity

Problem : Severe acidity from the past 1.5 years with a feeling of heaviness in the stomach and the stomach appears to have been bloated. Because of this appetite is low. Once in every two to three days I feel like vomiting to relieve my stomach. For this I take butter milk or tender coconut water and all the acid comes out after 10 to 20 mins of taking butter milk or coconut water. The fluid coming out is acidic that it causes a sore throat for me.
When the acidity is high, I dont get deep sleep, I feel as if I am still awake with eyes closed, I get dreams continuously and inspite of sleeping for 8 hours I feel that I couldnot sleep properly.
I also get headaches in the evenings because of acidity and once vomited everything would be fine. If I delay the vomits by a day or so, I get red color fluid at the end of vomit which is very very acidic. The vomits are atleast half a mug ful.
I dont have pain in the stomach, but I can feel there is another heart beat like thing in the stomach which I can feel constantly and in the nights I can feel my forehead/brain nervers stressed, If I put my finger just above my ears I can feel my nerves constantly expanding and contracting.

Reasons that I think could be:
- I have moved to a new job where the nature of responsibilities are high and I can see that the acidity is high when I am stressed out more.
- I am also driving to office which takes me 45 mins and the traffic is so bad that I get stressed even more.
- Acidity increases when I eat 'new' rice but am comfortable with 'old' rice
- When I eat sweets, acidity increases. Previosuly I didnot have a liking toward sweets, but from the time I started having acidity problem, I seem to have a liking for sweets.

About me:
- I am 33, male, 5'6', 62 kgs
- I am not a alcoholic or a smoker. I dont take Coffee, tea also. Once a while I take milk. I drink around 3 lts of water every day.
- I dont have any water during meals. If I take 2 or 3 sips also, I feel discomfort after the meals, I can feel the refluxes. Previously, before this problem started I used to take two glasses of water during meals with out any problems. Now even a sip is a strict no.
- Cool drinks is a strict no for me, if I take cool drinks or icecreams I can expect acidity the next morning.
- I do yoga (surya namaskara) and pushups in the morning. If I miss this, I feel heaviness in the stomach.
- I usually feel the acidity more in the evenings (and the urge to vomit). Sometimes I also feel it in the nights and the next day mornings are drowsy. I dont feel like getting up from my seat and moving around
- In the evenings when I have acidity I feel irritated and get anger with a slight provocation.
- My nights are worse when I acidity is severe, I dont get a deep sleep.
- Urine and stool are normal

Diagnosis underwent (around 6 months back):
- Endoscopy : Result - negative
- Ultrasound scanning: Result - negative
- The allopathic doctor told me based on the above tests that I dont have any ulcers but my digestive system is very poor. The endoscopy test reports say there are some erruptions on the lower part of oesophagus. The allpathic doctor prescribed pantocid dsr in the mornings for one month. I continued that and during that month - I was kind of ok, but not 100% cured. after that month, the problem started again.

Homeopathy treatment:
- I consulted a homeo doctor near my house and continue medicines for around 3 weeks with no result
- Then I consulted another doctor in homeopathy but I have to travel for 30 kms. I have been taking medicines with him from the past 1 month. The acidity seems to be under control, now the vomits happen less frequently - once a week. However if I take sweets, I get sour/acidic vomits immediately next day.

I am finding it difficult to travel 30kms everyweek and its one month that I have continued the medication. I feel that the medicines are controlling the acid that is generated but are not curing the root cause of why the acids are generated in excess.

I dont overeat, but have 4 hours gap between my breakfast and lunch and around 7 hours gap between lunch and dinner. I take some snacks between my lunch and dinner.

Please advise me what medication to be taken.

Thank you very much,
