Did I really hurt my chance of 20/20 vision after eating an edible after LASIK surgery?

Excuse my terminology if it is incorrect, but I had my wavefront guided, custom lasik, done last Friday on 5/22/15 around 430pm. I went through the usual nap and pretty much slept the rest of the night. My concern is the following Monday (5/25/15), I ate a weed brownie at night to help go to sleep. After the brownie kicked in, I did use artificial tears every 15 minutes until I passed out. Would the edible have cause over dryness while I was asleep and hindered my healing process?
