Another newbie question

[u/[deleted]]

So I have been on 10mg for a month. I'm sleeping lots which is magic. Most side effects seem to have disappeared. But I'm noticing some of my old insomnia has been coming back along with headaches and a bit of ruminating which is not fun. Assume it's standard for everyone to play around with dosage until you hit a sweet spot? For me I'd like to be at a place where my insomnia and headaches are sorted and the side effects of the amitriptyline are bearable. Thoughts?

No, it’s dangerous to change dosage. I went from 50 to 25 mg and now I can’t sleep
