A good friend of mine was telling me how she quit cold turkey after being a meth head for 2 years. She said she got the shakes , very bad headaches... woke up in cold sweats. Poor girl. Then finally, after one month of making herself not do anymore, cutting her ties with her suppliers and the friends that did that stuff - the cravings stopped. She then turned to excercising to help even further and she's been clean for 6 months now. So my question is - is it really all in your head?
