Four days ago I smoked some marijuana with my friend and I deeply regret it. I have that wierd disconnected feeling like i have a head cold but without any of the other symptoms. I get a little dizzy and light headed when I bend down for a while, and I have little appetite. I have only smoked pot a very few number of times before and I have never felt anything like this. Does anyone know what I'm experiencing? When will I be back to normal?

Thanks
