So I had been taking L-Tyrosine for a while for two reasons: 1) I heard it can be good for depression, and 2) People on r/HPPD had been using it saying it can help with HPPD (yeah I know...and here I am always saying to ignore them).
I took a little more than usual early Tuesday morning after no sleep. I ended up getting very disoriented, felt very weak, felt manic, and started having small hallucinations (not the HPPD kind, I mean actual seeing shit that wasn't there).
I became so disoriented I dialed 911 and was brought to the E.R.
My vitals came back fine, and they gave me stuff to calm me down. After sleeping most of yesterday and last night, I feel a lot better today, but still a bit shaky and anxiety-ridden.
I think my Dopamine levels were simply increased way too much by the supplement, causing basically all the symptoms you'd expect with high Dopamine levels.
