I don't drink coffee or soda. I may have chocolate here and there, but caffeine makes me too jittery. Even chocolate can affect my adrenals. However, I just started supplementing with D and have only been using 1000 iu. I'll start doubling that. TY : ) Didn't know there was a connection there. I'm trying it for lower back pain due to 3 bad discs... Russ had posted people with pain tended to be deficient. I have been taking b complex, too. But have to in the morning or even that is too energizing for me. Its hard being like this... Its like something is being overly stimulated in my endocrine system. You said you're diabetic Birdlady? I'm insulin resistant. Hoping to avoid that state. Just found out my sister is mildly diabetic... What do you know about the relationship with the pituitary gland there? Just not controlling the other stuff right? (To put is simply...I have a cold and feeling lazy and tired but still wired...drives me crazy. A "woman of few words" for me right now, though, cause I don't feel good).
