Mirtazapine
"On 15mg of this for last 3 months for depression ...OCD....sad anxiety disorder.  It didn't sedate me at all helped with sleep straight away took away anxiety after 3 weeks helps with OCD thoughts/harm ...all in all its a brilliant medication which worked for me immediatly keeps you calm and stable and just makes you happier. If you can get through first 2 weeks of side affects your laughing.  It's a great medication been on 2 before which sent me crazy. Plz do give it a try but do not miss doses as withdrawal symptoms appear quickly on this drug and are horrific to say the least"
