question regarding Melatonin

Does anybody know anything about the affect of taking melatonin for sleeping for people with auto-immune disorders.  My rheumy told me to take 3 mg a night for sleep since I've had some insomnia lately, and for some reason I didn't read the bottle until last night and it specifically says for people with auto-immune disorders NOT to take it.  Something about the fact that it can make auto-immune conditions worse? Would appreciate any answers.

Thanks Patty,

I actually have my nurse's e-mail address and was going to drop her a line to have her check on it.  I told them I had some problems sleeping when I was in there last week and told her I didn't like taking the Tylenol PM or other stuff because I already feel overmedicated and asked her for suggestions and that's what the doctor suggested.  It seems like you can search the Web and there is always an abundance of information when it comes to medical conditions - just not sure what to believe anymore.
