Guys I've decided.
After Weeks of blood tests and consultations with my two supportive GPs I'm finally at the end of my rope.
I'm going to ask for t3. I desperately need to convince them but I need support and evidence and as much research for my appointments tomorrow as I can.
Does anyone have any advice of anything that worked for them ?!
Many thanks
WLorenm, I doubt you'll succeed having only been on Levothyroxine for a few weeks. You'll need to demonstrate low TSH, high in range FT4 and low FT3 and it's entirely likely that FT3 is low because you haven't been on meds long enough yet. Good vitamin D levels aid conversion of T4 to T3.
You were so positive 3 days ago. What's happened to make you want T3?
It seems crazy but I think I'm being blindly positive. I'm willing myself better.
I still can't eat and the weight isn't changing. I'm at the end if my tether. 
Wlorenm, you've really not given it enough time. TSH reacts very quickly to replacement hormone but it takes longer for FT4 and FT3 to improve and FT3 takes longer than FT4. When your FT3 levels are good your hypo symptoms should be gone and you should be able to exercise and lose weight.
I have low tsh. And high in range vitamin d and t4. The labs don't send my t3.
Wlorenm, you can order private FT3 tests from Blue Horizon or Genova via thyroiduk.org.uk/tuk/testin...
I don't think it's worth paying for a test until your TSH and FT4 results have been stable for 3 months.
My GP stated that he could not prescribe T3 unless it had been advised by an endocrinologist and so I had to wait to see a consultant before being trailed on it. They do not repeat blood test until 3 months after commencing meds.
What did you say to convince him Wlorenm?
How much is he prescribing? 
Supplement brand recommendation
