weed hangover???

hey guys, so I rarely smoke, I probably have around 10 times in my life. 3 nights ago I got high and since then I still feel high? it was strong and I had more than I should have. it has been like kind of like a brain fog but my body is still going through an all over tingling sensation and I can't focus. i am trying just to enjoy it, but it is kind of scaring me lol. I only know of a few other people that have experienced this. anyone else went through this? if so, how long did it last?
