I highly doubt it would, but I thought I'd ask. Does MDMA have any interactions with large doses of Calcium? I'm Calcium defficient and need to take Calcium pills. Would anything go wrong with taking Calcium and E?
No I doubt that will cause any problems, I take multivitamins and calcium pills daily and have never had a problem.
JoshuaV might be right about the jaw clenching but again I'm not sure because the vitamin pills I take have Magnesium in them which is supposed to lessen jaw clenching.
