This is the exact reason that I am so glad we are on Zegerid. It doesn’t have to be timed around meals. That has been wonderful! I can’t imagine having to try to dose medicine 30 minutes before Sarah eats. There are definitely ways around your problem (as a few have mentioned) but if it does become a severe inconvenience, just know there are other PPI’s you can look into. 
I am really glad that you have been able to find support from this site. It has been wonderful for me and it makes me feel great to know I’ve helped someone else a little too.
