I know TSH is better done as early as possible in the morning .Having TSH and T4 done on the NHS but can only get T3 done at the private hospital . In 10 years I have never had T3 checked so because I never feel well thought I should get it done . Over the past few weeks I have been experiencing anxiety on waking ,and sweats and flushes during the day . My last TSH was done a couple of months ago and it was 0.39 ( 0.37-4.5) been on 125/100 alternate for a few years now . Should add it's 10 years since I had a period so don't think it's the menopause .
