TIFU by accidentally getting stoned at work

I work at a law firm. Boss keeps the windows open and I get really bad allergies in spring. Today I forgot my Zyrtec so I was having really bad symptoms, like could not breathe bad. Boss was like, we have benadryl. I've never taken benadryl in my life. I figure how bad can it be. I take two. I then read the package: may cause marked fatigue. I usually drink strong cold brew in the morning and I also take a daily steroid inhaler for chronic asthma, which can wire me so bad that i lose sleep. You can see where this is going. The combo of the coffee and inhaler and benadryl is bad, like I can't think and my hands are floppy bad. I feel like I ate a weed gummy. My boss is asking me to send important tax documents to high powered attorneys and I'm sweating. I cannot read the documents because I'm living in the time dilation zone. I have been moving in slow motion since 9:30 am. I have no idea how I'm supposed to accomplish anything like this. I tried to pick up the phone earlier and failed three times bc I kept dropping it. Coworkers think I'm actually high on real drugs. I cannot. think. I'm going to cry.

TL;DR I accidentally speedballed myself at work.
