Thanks to both of you for the suggestions. I take 800mg magnesium a day in divided doses. I used to take liquorice extract but now that I'm on adrenal medication, it interferes with that and makes me poorly. I think where I need to look is in my head. I've got worries about my job and I think the stress is affecting my adrenals and pulling me down. I often crave chocolate when this is going on. The past 3 days I've had stomach cramps, particularly at night; I felt very poorly indeed Monday night and thought I'd got food poisoning. Guess I could do with some relaxation therapy, LOL. I will start another chelation round soon; started one last night and forgot to dose this morning so had to leave it off.
