heartburn

So I have a Rx from the doctor for an acid reducer, I go through tums like candy, I'll drink the baking soda and vinegar mix about twice a day and I'll drink milk. It doesn't stop my heartburn!! It's all day, all the time and worse if I haven't eaten recently. I avoid all spicey foods as well as acidic foods. This is yuck...It makes it so hard to sleep. Any other suggestions?
