Hi. I Have Been Taking Remeron For Depression For 3

Hi. I have been taking Remeron for depression for 3 weeks now. Each pill is 15mg. The directions say to take one at bedtime but when I take a whole one, all I want to do is sleep, even the next day. I have been taking 1/2 most of the 3 weeks but am not noticing any difference with the depression symptoms and don't know what I should do at this point.
