I've been taking 25-50 mg of trazodone and 25 mg of sertraline for anxiety and sleeping problems. I usually only take 25 mg of the trazodone but I woke up in the middle of the night one night and took the other half and went back to sleep. That's only the second time I've ever done that but ever since some of the symptoms I had when I first started taking the two came back (really bad anxiety first thing in the morning). It was a few nights ago and I've only taken the 25mg half since. But today I took my sertraline and literally within minutes I think I had a full blown panic attack. It hit me really hard and really quickly. I took a small bit if my lorazepam to help but for a but afterwards my heart was still racing and my heart was pounding and now I'm feeling really nauseous and I have a bit of diarrhea. Can someone tell me what this is and what will make it go away. I can feel the panic is still there but its almost like the lorazepam is covering it up instead of making it go away like it usually does.
