I had drug-induced euphoria on my first full day on Ami and what felt like very little symptoms … so I went for a long run (about 20km, a bit excessive!) during which I did a sprint and pulled my shoulder really badly … I was in agony for days and couldn’t sleep on one side … you can’t win!
You’ll be fine … it’s an excellent drug, try not to get spooked.
There will be side effects, but for me they were sooooo worth it.
The first few weeks I took nortriptyline at 10mg (similar to Ami) were the worst. I didn’t actually think it was doing anything for my symptoms (if anything, they were stronger) and my frame of mind was not good. I saw better results at considerably higher doses and over time. Nort and Ami are slow-acting; some people see results quickly but for many more, it would seem, it takes weeks and months to see meaningful progress.
If I may speculate, perhaps the anxiety is a function of expectations. These meds can be a long game; if you can, work toward acceptance that you’ll be able to assess progress in weeks/months, rather than days. See if it’s possible to feel calm and encouraged knowing that you are on a good path and going in the right direction.
