No more choking myself to exhaustion. However
for some reason this
is no longer on the market (this may be temporary). However
what you can do is take an over-the-counter mucolitic. The only worthwhile one is Guaifenesin. You don't want to get Mucinex which has other ingredients, but plain guaifenesin. Also, take 500 mg of vitamin B5. That is also a mucolytic. No side effects.
Are you seeing a family doctor or a lung MD?
