Spiriva
"I've been on Spiriva for about 15 years or so. At first it helped my breathing a lot. Now, not so much. I've constantly battled the capsule not working. After contacting the mfg years ago, they eventually they reimbursed me for a box of the medication. They told me the amount of medication in the capsule would fit on a pin head. One day this week it took 3 capsules before finding one that worked. The plastic capsule sometimes seems to explode when you squeeze the lever to poke the hole in it. When it makes "that sound" of loud popping, after I try to use it and it doesn't work - I can open the handihaler holding the capsule, take the capsule out and hit it on my palm and tiny pieces of plastic fall out in my hand!"
