depression
"I finally wound up on Remeron about 15 years ago (circa 2002), after going through many SSRI antidepressants.  All of the SSRI's I have tried have caused sexual side effects that I don't want to tolerate (delayed ejaculation).  Remeron does not do this, in fact it seems to make it very easy to achieve orgasm.  The only downside to Mirtazapine is that it increases your appetite and you have to fight the urge to eat too many carbs.
It controls my anxiety, depression and OCD excellently."
