Sense of smell and taste

Good afternoon,
Day 4 of no weed, and have noticed things. Sense of smell and taste has changed a LOT. Cigarettes used to not phase me, and now they’re absolutely horrible to smell on people. I walk past them, and get a horrible stench. My sense of taste however, has sharpened!
Headaches have subsided for the most part, just feeling tired after getting 9+ hours, and a cup of coffee.
Have gotten a lot better, appetite is still crazy high for some reason. Dreams still crazy realistic, but not a single nightmare yet.. mind is still blank.. hopefully it’ll change sooner than later?
