Hi Rosie, I think you'll find there are many MANY women who have this,I used to have silent reflux,which would make me nauseous too,was given omeprazole,which is pretty much what you've been given,only I think it helps more with acidity than lansoorazole. Also with meno,comes intolerances to certain foods,that you may not have had before,is there any time of day this happens or is it constant?
