Review: Only brand I buy - This is the only thing on the market that really works for me. Used to be a Nyquil user but this works much better.
Review: My favorite cough drop. - I always keep some of these in my desk and with me during air travel. They have been a real butt-saver when I feel I’m going to cough in public. I have passed them to hoarse singers on stage, and travelers that have dry throats. They have been a hit.

## Questions & Answers

**Q: do the pills work as fast and as well as the liquid?**
A: Yes, however the liquid pills are a bit easier to swallow.

**Q: What is the current expiration date as of 4/20/2016?**
A: Hello.  The current expiration date is May 2017.  However each manufactured bottle might have a different expiration date.  I hope that helps.  Thank you.

**Q: The pill is too big Can I cut it?**
A: I don't see why not; there's no liquid to spill. Cut it it 1/2, hopefully you won't have splinters of pill or a a bunch of dust.

Try it once, if no go, you only wasted a pill

**Q: How long does this take to work to stop you from coughing**
A: It usually works for me within one hour.  It also helps loosen the gunk in your lungs that is making you cough but beware that once it is loosened, you will be coughing it up and out!
