He's pretty switched on my GP but I'm going back to see him on Friday so I'll list the side effects I'm having and talk to him about them. I'm thinking of going back down to 450mg as I don't think I noticed the water retention so much at that dose. I've just ordered a big tub of Epsom salts as they're supposed to be really good for aches and pains and helping withdraw toxins. Thanks Suzi. Hope you're well x
