I have just ordered some Thyroid-S and would be grateful for some help in changing from Levothyroxine. At the moment and for many years I have been on 75mcg Levothyroxine and until the change from Goldshield Eltroxin I was doing well (apart from weight gain of 3 stone). Since change, and having tried all from this country (and more) I am now experiencing all old non-treated symptoms. If necessary please PM me. Not sure of posting guidelines on this.
