"my husband suffered from migraine headaches throughout his life. he was prescribed stadol ns. his migraines became more constant as his body craved stadol. he was going through 5 bottles a week and had a callous on his palm from using it. this was back in 1996-1998. he went through rehab.  it did stop his migraine, just to bring them back stronger and more often. please ask your family if your personality is changing. please listen to them."
