I Took My Zoloft Tonight With Water But Fell Asleep

I took my zoloft tonight with water but fell asleep shortly after. I just woke up (2 hours later) to burning in my chest/ esophogus. I have eaten 2 pieces of bread, drank water and almond milk, ate a banana and tried hot water. All helped temporarily. It feels slightly better. What else can I do? I do not have antacids- use a lot of home remedies so don't have much on hand.
