I have been on it over a week now... however have had weird sleeping patterns for a while, I tend to go between 3-5am at the moment, have done for about a month... so I've been taking the Mirtazapine about 40 mins before I am ready to go to bed. Can I go from taking it around 5am straight to taking it around say 1 or 2 am - to try and sort my sleeping out to a more "normal" time? Or should I try it at 4am, 4.30am, 3am, 3.30am etc?
