Try amitriptyline for sleep, it's pretty amazing.
"Amitriptyline acts primarily as a
serotonin-norepinephrine reuptake inhibitor, with strong actions on the
serotonin transporterand moderate effects on the
norepinephrine transporter.
[31][32] It has negligible influence on the
dopamine transporter and therefore does not affect
dopamine reuptake, being nearly 1,000 times weaker on it than on
serotonin.
[32] It is metabolised to
nortriptyline—a more potent and selective
norepinephrine reuptake inhibitor—which may complement its effects on norepinephrine reuptake.
Amitriptyline additionally functions as a
5-HT2A,
5-HT2C,
5-HT3,
5-HT6,
5-HT7,
α1-adrenergic,
H1,
H2,
[33] H4,
[34][35] and
mACh receptor antagonist, and
σ1 receptor agonist.
[36][37][38][39] It has also been shown to be a relatively weak
NMDA receptornegative allosteric modulator at the same
binding site as
phencyclidine.
[40] Amitriptyline inhibits
sodium channels,
L-type calcium channels, and
Kv1.1,
Kv7.2, and
Kv7.3 voltage-gated potassium channels, and therefore acts as a
sodium,
calcium, and
potassium channel blocker as well."
Interesting that it has a function on the potassium channels.
