so I took 280mg of ritalin and had a great high but then on the comedown I had a panic attack because I used to take ssri (fluoxetin) and I just stopped taking them 2 weeks ago. now I am shitting my pants because I am afraid of getting Serotonin Syndrome. I did not do enough research because when I checked in the pharmasy website which said thats its no problem to mix ritalin and fluoxetin. but after I did some more research because I was having anxiety from the knowledge that I was still had some ssri in my body and now I am feeling still really panicked and I am still feeling tge Ritalin which is also the reason of my poor grammar. I have a really bad headache now and my heart beat is still way to fast. I can't calm myself down even with 1mg Lorazepam.
