Guys I am completely new here

Okay so long story short, I had absolutely the best kind of sleep you can imagine. Until I was put on antidepressants in 2016, I have been fighting hard to go off of them and managed to get on 5.1mg of mirtazipine and I was doing good, sleeping about 10 hours but you know what happened boom all of a sudden I wake up and I am not rested, I wake up at 3:00 and I am not rested. It's crazy really. I went back 15mg of Mirtazipine although kinda manageably I sleep like 8-9 hours but I wake up not rested at all, I don't know I always feel like I need coffee. I am unemployed, 29 years old. So yeah my questions is, I am thinking of going to a psychiatrist again, even though I hate them.

what are the common pills prescribed for insomnia? and what remedies are often used and discussed commonly on this sub? Other than electrolytes?

Like any information you have that you have gained, any experience anything that you could share I would much appreciate it. Right now I am just existing you know? I am not living. I don't want to increase Mirtazipine because it took me 3 years to get it down to 5.1mg and I still plan on tapering it completely, I am not happy that I am taking 15mg right now. Mirtazipine makes you gain weight, I don't like that about it. I hope I made sense. Thank you.
