Please pray with us!!

So, I have this new friend who started showing up a few months ago.  I vomited at 2:45 am because of him.  His name is acid reflux.  I can honestly say, I don't want this relationship to continue, but I don't really know how to get rid of him.
The whole thing started a few months ago after one of my migraines - I should note here that during a bad migraine, I throw up between 6 and 10 times in anywhere from 5-8 hrs.  The day after my migraine, I ended up throwing up from severe acid reflux - and the burning etc stuck around for another 4 days after that.
Unfortunately, this repeated itself with the very next migraine I had.  Throwing up the next day due to the acid, then severe discomfort for the next number of days.
I mentioned to a friend here the issues I was having.  She gave me a 2 wk course of omeprazole.  It really helped and I hoped that I was over a hump.  See, my theory was that I may have damaged something in my throat or esophagus or whatever due to all of the vomiting from my migraines.  I hoped that taking this would give it a chance to heal and then all would be fine.
So, fast forward a little, I started having some bad issues with acid reflux without having had a migraine just prior to it.  I started debating about seeing a doctor.  There is a hospital here that is Swiss owned.  Unfortunately, the Swiss doctor that was there has now left and they don't have a replacement for him.  Real communication with a Tanzanian doctor is questionable.  Anyway, another friend gave me Zegerid OTC to take, so I decided to go ahead a start that 2 week course b/c of the issues I was having.
Wonderful!  Not a single problem - not even a little heartburn - the whole time I took it.  Unfortunately, the course finished on Wednesday, and Thursday night my friend had a surprise for me.
I can get more omeprazole here at a pharmacy type store, but I don't know that that is a permanent solution. Avoid spicy food, acidic food, and avoid greasy food, don't eat late at night, raise the head of your bed up.  I try to do this, and really didn't eat anything bad yesterday.  The only thing I haven't done is the bed thing.
I guess I would really like to get rid of this friend and right now, I don't really know what to do except pray.
