I completed a 21 pill pack of Medrol almost 2 weeks ago and I'm STILL suffering from bouts of anxeity and insomnia. I find it very difficult to fall asleep due to nervousness and once and if I do fall asleep, it's not for very long. this all started when i began treatment with Medrol and I had terrible insomnia on it and now what seems to be off of it. Is it possible the medication could still be lingering in my body? Or am I possibly just working myself up into believing that it is?
