Nonstop High?

Okay so just recently within the time span of a month I started smoking more often (every weekend or so) but this past week I have smoked nonstop and I knew I was sort of screwing myself over so I stopped after Wednesday. I have felt a nonstop buzz for the 48 hours and it's not intense but it's really screwing up my train of thought and memory to an extent. I don't really know what's going on or if this is normal and I'll be fine because Ive never been this fucked up before. Someone give me some help or advice???
