lucie, if you only recently had your fillings out beware of the methionine, might mobilize mercury, I'm only taking it because I'm sure my heavy metal levels are way down. Also do some research on methylation and the symptoms associated with methylation dysfunction. Methionine is excellent if you are an under-methylating type with an overload of histamine. but over-methylating it can be harmful. Also if you decide to take it definely take it with good quality zinc, magnesium, b6 and make sure your getting calcium in your diet. Just be cautious of it, I am very cautious of it still even tho its helping me.

The reason why you prolly felt good on the holiday was that your body stopped detoxing when you ate and drank whatever you wanted, believe me I had that experience too especially when going to the beach, you feel great! But yea when you got home and back on the diet and supps your body began detoxing again. Mayb this is what happened, I'm just basing this on what I went thru.
