My daughter is bi-polar 2. She has been diagnosed with fibromyalgia and has sever pain, quite often. She has been prescribred hydrocodone 7.5 for pain. She takes Ativan, and Lamictal for her bi-polar and is well controlled. Since starting the hydrocodone, she is acting MEAN, difficult, arguementative. Is it possible that this medication could be affecting her personality because of her bi-polar. She seems out of control....not like herself. This is only her second day on the hydro. and her personality is different! I'm nervous about this medication.
