Hi nicola, i only took 25mg selenium yesterday and feel sort of alright, im not sure cos im always getting symptoms, they come and go. Im always needing to eat nearly every hour. No, i havnt started yet with the DMSa, too scared, at the moment my anxiety and nervousness come and go and arnt as bad as a few weeks ago, im scared of getting like that again. it would be so much easier if i lived on my own. but i have a house to run with 2 kids, i know i will have to start soon. Can you tell me how you are on it and your symptoms?thanks.
