Clindamycin
"it's too early to tell if it's working it's just the difficult side effects. I've been dealing with brutal acid reflux and pain after swallowing (as soon as food hits the top of my stomach there is severe cramping and pain.) However, these are tips that have personally helped me quite a bit. I am not a professional in anyway:

1. Drink with a TON of water
2. Never EVER take on an empty stomach
3. Eat with a large NON-acidic meal; 
Good: bread, rice, potatoes, bananas, milk, plain chicken 
Bad: Citrus fruit, tomatoes, oils, anything fried, anything carbonated, anything with lots of spices.
4. Do not lay down right after taking
5. Take a probiotic but take at least a few hours before or after taking this"
