Have been on T3 only for a week having had various combi doses of T3 / T4 with varying degrees of success.
Am now on 40 mcg T3 and having bad 'run out' symptoms. I've been taking them: 20 mcg at 7.30 pm, 15 mcg at about 2 pm, and 5 mcg at bedtime. Yesterday felt so 'run out' took the last 20 mcg as one dose at 1 pm and was fine until about 6 pm then wham!! It isn't just tiredness it's headache and body pain that recurrs.
This morning, felt lousy even after first dose of the day, so took the remaining 20 mcg 2 hours later. Just beginning to pick up.
I know that Shaws and others take their whole daily dose as one dose in the morning so I'm trying that. Just mithering that I'll be crashed by early afternoon.
Interested to know if anyone else on T3 only takes as one dose. I think I may need the backup of some T4 to fill the gaps. Felt better than this on 30 mcg T3 and 50 mcg T3.
Thanks for reading x
