To give you slightly more information:
I checked and both names are generic.
Mianserine is an antidepressant but can be used at lower dosages as a sleeping aid. I noticed that it helps me go to bed.
Quetiapine is an antipsychotic. It is also used as a sleeping aid at lower dosages but I have seen counterindications on account of the heavier side effects. I noticed that it didn’t make me that sleepy but it keeps me from waking up every few hours and helps me go back to sleep when I do wake up. A few friends of mine find the hypnotic effects too intense and need to take it at the end of the afternoon in order to hear their alarms in the morning.
Hooray, already on both of those types of drugs for other reasons (not mental health, a nerve disorder). So they probably won’t help. Thanks though!
They still might depending on what you tried.
For example some antidepressants tend to give a bit of a jolt (e.g. fluoxetine) and are usually taken in the morning.
Most of the time you get some SSRIs as a first antidepressant which usually wake people up. Mianserine is a tetracyclic AD with a whole different set of effects.
