If you've tried this or take it, what benefits have you experienced? My doctor gave me this to try. She recommended taking half (250 mg) of the pill for a few days because people experienced a lot of diarrhea. I didn't get diarrhea but I had trembles and insomnia, so I took one whole pill. I swear, I felt strange. I had depression, tremors, insomnia and incoherent thoughts. I will continue this medication until I can determine if there's a change in my breathing.
