I have read that some of you are on LDN. My Dr has just given me a prescription for this - 3mg to be taken in the morning. I have the imbalance in the TH1/TH2 of the immune system, and he said that it would bring the TH1 up to better functioning. Could u pls advise the following: ositive/negative effects of LDN, and how long before kicking in. o any of u take Armour thyroid with LDN - is there any contraindication that u have found? :I read on the web that it should be taken at night, but my consultant has said the morning - any suggestions? oes it interfer with your sleep? oes it make u feel hyper? With many thanks Nickname.
