I had an appointment with my doctor yesterday and we discussed either increasing my dose of nortriptyline or switching to mirtazapine. The past few weeks the pain relief of nortriptyline has faded and the sleep benefit definitely wore off a while ago, so I added hydroxyzine for insomnia. I actually suggested mirt because I heard it’s great for appetite and weight gain (I’ve been underweight for 2 years unable to gain anything partly due to early satiety), and I’ve done great with the hydroxyzine with is also an antihistamine. She was open to switching right away and said I would taper by taking nor every other day for a week and then starting mirtazapine at a low dose. I got scared of the side effects of withdrawal and decided I would wait until adjusting a few other of my meds (might need to do another round of antibiotics for h pylori test), but I was wondering if anyone has experience switching between these? I saw some rough starts to mirtazapine here which makes me worried.
