depression
"I took this drug for about a year and then had to quit when I lost my job and my new job didn't have very good health coverage. After being off the drug for about a year, my depression was worsening (would start sobbing over the smallest things) and I decided to restart the medication despite the cost. 

Having been off the medication for a year now, I don't really remember if I initially had any side effects - though it's worth noting that I started at 5mg and worked my way up to 20mg, whereas this time I'm just restarting the 20mg. I'm almost a week into it and I'm experiencing constipation and itchy skin. It's not pleasant but I'm sure it'll go away soon. This med works really fast, I already feel my depression lifting."
