I have Paul Robinson's T3 book and have attempted the circadian method. I was taking 15mcg T3 split across 3 doses; the v early am dose (4.30am), then at about midday and late afternoon. I didn't feel much in 15mcg so one morning I upped the early morning dose to 10mcg. I literally shot out of bed at 7am with none of the usual brain dog or drag of fatigue - it felt amazing. That day I took the other two 5mcg doses as usual and went to bed slightly later than my usual 10pm. That night my sleep was horrific. I was dreaming the most awful things and waking up every hour or less sweating and in a panic. My adrenalin must have been during off all night or something. Anyway, I couldn't take another 10mcg dose because it frightened me too much. That window if wellness that I experienced was amazing though. So this is why I'm trying armour again and not pure T3. Can anyone explain the reaction that I had there though? Was it simply an adrenal thing and does anyone know how to overcome such a problem? Will armour cause the same problem or will it be gentler? Thanks.
