I have a few questions. I get the shakes every once in awhile it starts off by me feeling chilly then i twitch it is not that noticeable. I used to use cocaine and vicodin and alcohol. Is this from brain damage or nerve damage. I told my neurologist about it and he prescribed me gabitril. I have not started taking it becuase he did not even explain to me what is going on and what the medication does all he said was i was going to feel different, and iam scared because i have some mental issues that might get worse if i take a weird drug that my body will not like, help any suggestions. Is anyone on this drug that can tell me how it makes them feel?
