I have been taking 15mg of mirtazapine for 3 nights for insomnia. First 2 hours to fall asleep (pretty good for me) the 2nd night it took me 4 hours and the third night 6 hours! I had also taken 25mg of promethazine too!
I know it can take up to 8 weeks to feel the full effects if it’s taken for depression but I would expect this medicine to work instantly for sleep.
Has anyone else taken this for insomnia and if so was 15mg enough?
