Which drug did you get prescribed, if you don’t mind me asking?

As someone with years and years of, err, experience with sleep issues, I’ve learned a thing or two about sleep aid medication. Most of the ones that fool with your GABA receptors tend to be pretty terrible for sleep quality and cause dependence and all sorts of other issues. Pretty much one of the only sleep aid medications that won’t fuck you up with longer term use is mirtazapine, which is an antidepressant but also inhibits your histamine H₁ receptors (like older-type antihistamine drugs) so it’ll make you very sleepy. Used in super low doses (something like 3.5mg, where the lowest used for depression is usually 15mg) its SSRI effects don’t really kick in and it can actually increase sleep quality, and for most people at these low doses its only downside is that if you take it too late in the evening you’ll have a hell of a time wrenching yourself out of bed. It can lead to the H₁ receptors getting desensitized in longer term use, meaning you can build up tolerance to the sleep aid effects, but that’s solved by taking a few weeks off of it if you do notice it getting less effective.
