I took it a very long time ago but I was allowed to take it all at night for the same reasons. I just didn't get to stay on it long because it caused EPS. So I think I was on it 3 months or something and then had to stop which was fine because I was doing better and was able to manage without an AP for quite a while (a year, maybe 2) after that. I don't think I was on a huge dose because it knocked me out and made work hard.
