Currently trialling T3 (10mcg) a day alongside T4 (75mcg) to see if it helps with combating brain fog, exhaustion (have Hashimotos).
Bit of a long story but got first months supply via endo's private prescription. Seemed to help with the exhaustion and had no other problems so asked for another month's supply. However I had a weeks delay in finishing the first batch of T3 and starting the second batch (endo didn't send through the second prescription in time). Two weeks into the second batch of T3 and have had a constant headache since starting it. Not an awful pain but pretty constant.
Both batches of T3 were obtained through the same chemists.
Starting to get concerned - is this something that has happened to any one else?
