OP with update. THANKS!!! Great suggestions. I retried the green muscinex the DM one that was jittery to me before. Well I just did one tablet last night and did the air vaporizer and coughed VERY LITTLE and slept 4 hours. So far so good! Except this morning when I woke up I felt as though I could hear ocean waves though I live no where near the ocean. Something isn't right BACK to the dr. I have a middle ear infection and a yucky one at that and a suspected sinus infection. I am on 3 antibiotics (one of them being the cough pearl that I think is working for me!)....SOOOOO pressure definitely not as bad and energy level up!
