Hi @
SquarePegGuy that is interesting. I am not familiar with that med but I have experienced that a small dose of Mirtzapine induces sleep much better than a 30 mg dose. This was recommended by the prescriber.
I think buying overseas meds has a risk that they may not be the dosage on the label. Try US made meds if your pharmacy has them.
Also you might tell the different symptoms of the higher dose and ask your prescriber if you can try a lower dosage, but the one site I checked says the recommended adult dose is 150 MG.
