Maprotiline
"I have been taking maprotiline for over 35 years and I am still taking it (there seemed to be a shortage for a while about 2 years ago but Walgreens still carries it). I started having panic attacks with the onset of my allergy to dust mites when I was a teenager. In my 20's, I went into a deep depression and couldn't sleep for 3 months. I started taking maprotiline and 3 improvements occurred: 1) My depression subsided and then went away. 2) My panic attacks stopped. 3) The almost daily sneezing episodes associated with my allergy subsided, and now, they occur maybe twice and month. My runny sinuses also dried up considerably. I twice tried taking myself off of the medication--it didn't work. All problems returned after about 10 days."
