Did you mean: Hi, I have bipolar disorder. I just took my 400mg of my bi polar medication lamictal with a peppermint supplement my brother asked me to try. I took it about an hour ago, since I've taken it, my mood has completely changed for the worst. I'm violent, which is completely out of character for me, and I'm very shaky and jittery. I also have a past history of liver problems due to galblatter surgery gone bad, and my liver is aching a little. Is there anything I can do to stop feeling this way? I appreciate you in advance for taking your time to assist me. I am a 29 year old female, my height is 5'6, and my current weight is about 240.
