Thank you for your reply and info.
Oh, makes sense. As Linda Esposito helped me realize that when taking in liquid, day or early evening, 3+ hours before bed, have something that will absorb the liquid...so the same when taking Mucinex/Guaifenesin.
I need to start the evening walks, thanks.
Question: Had you been told you have Acid Reflux or Hiatal Hernia????
