The right diet, PPI for reflux

Hi, I need a lot of help, but also hope my post might help someone else in some small way. In January, I began to produce a lot of saliva and experience non-cardiac chest pain. The pain followed a slight change in my exercise regime (ab exercises) and the saliva was a gradual development. I am also a keen cyclist. Interestingly, i also had slight constipation when the chest pains started.

An upper scope showed grade 2 oesophigitis and my gastro also remarked that I had a lot of acid (how can he tell that without a ph test?). He said i would be taking nexium 40 mg for at least 8 months.

Two weeks ago, I reported to my GP and said I was getting a lot of acid, indeed, hot burning acid on my tongue and in my throat. I would also prduce loads of muous (reaction to the acid?) and suffer very bad asthma style attacks. I am an asthmatic, but I have never used the reliever as much as I have in recent weeks. My GP said that it was "all in my head" and actually wrote a referral to an anxiety specialist. I was pretty angry and with good reason because on Easter Saturday, I developed full blown laryngitis. A second doctor at a Government medical centre thought for sure that it was reflux related and precribed more antibiotics.

So Doctor number 1 wouldn't know a reflux symptom if he fell over it. Moreover, he would not even consider the possibility that the Nexium might not be working in my case or, indeed, causing unbearable side effects. So off I go to a new doctor. The nexium 40 mgs stays, but he adds tazac (nizatidine), a H2 blocker. I take this tablet (150 mgs) two times a day.

I am now following the dietry restrictions pretty closely. I have given up alcohol, coffee, acidic fruits and tomatoes/ mints. I never use to drink softdrink or fruit juices to begin with. I do drink water which amazingly seems to trigger acid breakthroughs on occasions. I have asked my wife to tone down the spices. I eat a high fibre breakfast (with added almonds and psyllium husks) with soy milk. I don't eat within 3 hours of going to bed.

I am not beating this curse yet and I have not found a drug or diet regime to control the acids. On a positive, the chest pains have abated and I'm no longer anxious about them because I know they are not heart related (angiogram clear). Ok so here come the questions:

(1) The doctor has given me a sample of somac to take (after I run out of Nexium) because unlike Nexium it can be taken morning and night. Is it normal in the US to take 80 mgs of somac a day?
(2) What is the correct title of the specialist who deals with LPR? I feel I probably have this, although also wonder whether the Nexium is actually causing this problem.
(3) What is the best milk to have on your morning cereal? I am having soy milk (which is about half the price of goats' milk here), but will switch if I'm given good reasons to do so.
(4) I live in Australia and I'm seriously considering laparasopy. However, naturally, I need to do all the tests before doing this. In addition, I will have to wait another 10 months before I can use my private health insurance which I have only recently joined. Feedback on the experience of others with this surgery will greatly benefit me and possibley others.
(5) What antacids are safe to have with my medication? It is going to be a long 10 months for me if I have to go through this on a daily (even hourly) basis.
Thanks very much for all of your help and for providing this forum. I really believe that the US is way ahead of Australia in combating this horribe disease. If I find a solution to any or all of my problems, I sure as hell will post it here to help others.
