I had a similar issue. I went to see my GP/OB and she's prescribed a medication called Omeprazole. It has worked a treat! No heartburn for me anymore :-)
I finally took Zantac, since i was relying on tums and they would stop working after 15 minutes. Eating too many tums is bad, and just changing my diet hadn't helped since even water gives me heartburn.
yes i had it and sometimes still do. I stopped eating right before bed , limited spicy foods and greasy and now i have it under control
Every night for the last 2 weeks.. ughhh i hate it
