I had a weird anxiety type reaction to eye dialation drops. heart was beating 90-130 bpm and hard. is it harmless? how long does it last? any harm?

Hopefully, all's ok: I expect that you woke up today w/ no lingering eye drop effects. But, when you know you have anxiety issues - esp medical ones - this is not strange. Talk w/ your providers ahead of any procedures. Ask in detail about what to expect and how to handle your usual reactions. I believe those are harmless after they wear off. But ask - always - w/ all Dr's. Best!
