I just wanted to "2nd" the pituitary thing. . . . I know someone who had a pituitary tumor (not from drug use though) and he was NEVER the same after the tumor was removed. . . . complete personality change, & not in a good way. So, if there's a chance that opiates cause issues in that dept, that's just another reason to stay off of them!
Very true. FYI though - women lose their drive for sex also when using opiates.. probably many reasons for this.. Just another thing addiction steals from us. Congrats on giving up on the drugs!
