Trying some new medication

I tried 20mg of sodium raberprazole back in February or January.  It
seemed to help a little bit.  Haven't taken anything since then but
have just come back to the UK had my throat looked at by a Brit ENT
doctor.  It is my throat where I seem to have all the problems.  He
didn't think i should see a gastroentrologist and just leave it.  He
couldn't find a problem in my throat.  Anyway, didnt have time before
coming back to Japan to see a gastroentrologist anyway so went to my
family doctor and he gave me 20mg of omeprazole and 10mg of
metoclpramide and said play with it to see which is more affective.
Any advice on trying out these two medications.  Should I try them
while relaxed in Thailand where i am now or stressed at work in a few
weeks?

A thai pharmacist recommended Cisapride.  Any good?
