I can only imagine how you feel with your Reverse T3 at 25.5. Like Vince stated, it needs to be less than 15. Here is some very good info on what it is, what causes it and how to correct it with T3 med cytomel or its generic Liothyronine.

My reverse T3 was 28.1 back in Feb of this year and I felt like I had been run over by 2 trucks. It was caused mostly due to low iron/ferritin from blood donations and also I had a very severe sinus infection about a month before and took several rounds of antibiotics to kick. Took me about 2 1/2 months to get it down to 13. Unless the underlying cause is corrected, just stay on the T3 med until you have identified it and fixed it.
Good luck and keep us posted.
