Well, for the past month i have noticed that my head twitches. It moves uncontrollably in a forward motion. My head moves quickly forward and backwards, it is really embarassing, and im not sure y. I have smoked pot before and it use to happen when i smoked pot but i didnt realize it. Now even when i don't smoke now it still happens. i haven't smoked in about 2 weeks. I went to see a doctor for a check up and he said that i was completely fine. Recently, i have noticed that sometimes my muscles in my legs cramp up, and start to twitch - but thats once a day. My Head moves in a forward motion ALL THE TIME! Its like im a Bobble Head toy... Any Help?
