Hiatus hernia

I have had this for past 31 years ( pregnancy caused it) and for past 20 years had been taking the branded drug pepcid which became unavailable a few months ago and i can ony get the generic version ( famotidine). I have found the generic version is not as good. I have always had the odd week where nothing seems to get rid of the constant heartburn and this seems to follow a sort of pattern so may be hormonal.

My Dr suggeted I change to either ranitidine or omeprazole to get better control. I am loathe to take omeprazole as this is so strong but has anyone taken ranitidine>
