I was shopping for groceries with my daughter. When we were done, before we left the store (Wal-Mart), I stopped at the bathroom. Right next door in the men's bathroom there was an EXTREMELY strong small of pot. Like someone just lit up. By the time my daughter and I got to the car WOW full blown migraine. This explains a few other times my migraines have hit. Shocking....of all things thou, the smell?? It's now day 3 and still here. Ugh. Another long one. Anyone else affected by this? I can't be alone.
