Mirtazapine is in the same category as Amitriptyline which is what I use daily, perhaps my doctor thought I could tolerate this medication but it didn’t help, I have had my share of medication but Mirtazapine was very scary for me, I recall having symptoms of restless legs and I was so worried about it because the sensation was very strong and foreign to me, it’s interesting how a med can work wonders for some people and be a proverbial nightmare for others.
