These are my most recent results:

Last result (29/4) was taken after I spent 2 weeks in the heat of Turkey. I have always shown an improvement in symptoms in hot countries but this is the first time I've actually managed to get a blood test done since I realized this improvement in symptoms was temperature related. I was doing 2 weeks of watersports for about 6-8 hours/day so not exactly a restful holiday in the slightest! I've spent all this week exhausted and now have symptoms of a cold and feel pretty rotten. I was hoping for a lower T4 (possibly not this low) and a higher T3. Yes it's higher than last time. Maybe I needed longer in the heat for better results?
My FT3 has never been this high before. Often it's below range. The gaps are because the hospital lab does it's own thing despite FT3 being requested. Both the last 2 times we've had to call up and ask for them test for it. IDEALLY I think my FT3 needs to be mid-range at least; either through a higher dose of thyroxine or combined T4/T3 if I can get it.
Why has my FT4 suddenly dropped off? Does this mean I am undertreated still with Thyroxine? Should I give 125 daily another chance? Is this related to better conversion? I'm HOPING to get FT3 at my specialist appt next week.This is the LOWEST FT4 I have on record except for when I was first diagnosed and it was 9.4 with a TSH of 33 (They never did FT3). This is also the second time ONLY that my FT4 has been within range (it's usually 22+). I've been complaining of symptoms since I've been on Thyroxine (March 2011). I've been on all three doses listed before but they always put me back because my FT4 is "too high".
I believe when on a higher dose you get an initial spike in FT4 as the body gets used to it then it drops off - I'd like to know if anyone else has had this at all?
