I have noticed when I have done methamphetamine that my legs tend to get Charlie horses a sometimes and my boyfriend has been suffering from his feet drawing up to wear his muscles are very tight in the bottom of the his feet and his tow will sorta get stuck in one positin.but I would like to know how common is this with this drug . and how many other people have this happened to them when they use this? Ooh n btw its not a substance i commonly use. anymore and I'm thankful to be able to say anymore.
