Folks tend to think supplements are all ok for longterm use, and I've NEVER seen this about melatonin! Thanks for the heads-up because my husband already has a chronic health problem that an autoimmune problem would devastate! He just started using melatonin, so I'll tell him to go a bit slower on it!
Bad part is, one of the worst side effects of his daily meds is insomnia - which he already had to start with!! ARRRGGGG!! Medicine!!! Can't live with it, can't live without it!
