"mirtazapine is a good medication! my experience with it has been positive! it got me sleeping when i was unable to sleep at all for 3 weeks due to severe to extreme depression! paxil made my depression worse; mirtazapine reversed my severe depression in 4 days at 15 mg! i wasn&#039;t able to sleep more than 1 hour a day for 3 weeks! also was extremely hopeless and sad! all i could is to sit on the couch unable to leave home! i had no energy! i was scared to take this but i had no choice! it helped within 4 days! the sleep improved slowly on it over a few weeks but my sleep was still fragmented! it does not fix sleep right away! it took about 4 weeks before i could sleep properly! it took me about 2 months to adjust and feel normal on this med"
