Am I the only one?

Re
I smell EVERYTHING! I hate it I really do. I sit in my bedroom and I can smell my neighbor smoking on the OTHER side of the house.  I sit in the living room and I can smell the half full trash. I'm eating lettuce and I can smell it's smell. I didn't even know lettuce HAD a smell... I really don't like my heightened smell.. Anyone else going through this too?
