Hi...have u been checked for a hiatal hernia?...the hiccups sounds like it could be a possibility and u should be checked.
A good chiropractor can do manual manipulations on hernias to help move them down and this helps with all the hiccups and reflux...it calms it down.
Eating less than 3 to 4 hrs b4 lying down can play into ur issues as well as greasy chips and chocolate r not really advisable with these issues....
Sometimes gerd can be a result of other meds, so do look up ur contraception pill for side effects.
Some meds should be taken with food to allow a safer absorption...do look at recommended timing for ur meds, u may want to try to take them with ur dinner.
