anxiety
"Was on this for about a month.  Went from 5mg 3 x a day to 30mg 3 x a day.  Saw improvement after about 2 weeks for about 5 days, then anxiety came back strong.  Always had sleep issues but this medication definitely exacerbated them.  I had to get off as it was giving me no benefit and my sleep was only getting worse.  Also had pretty bad brain zaps the whole time but probably bc I increased the dosage every 5 to 6 days.  I also have treatment resistant anxiety/depression (tried paxil, zoloft, prozac, fetzima and pristiq.  Zoloft helped me mostly, all others didn't work or made me worse) so this might work for others but did not help me."
