In a search for a nebulizer machine that worked on both plug in and or batteries ( which I could not find) I came across a "mesh nebulizer" on Amazon for 49 dollars US and purchased it. Used it and I am so mad I had to go threw so many gut wrenching attacks not knowing about this wonderful device that makes the medicine much smaller than a regular nebulizer which helps it get down deep into my lungs. Why on earth did my doctor not tell me of this device? YOU?
