Please go to the T replacement forum.
In the 2nd post of the one sticky there, please see links to these topics:
- advice for new guys

Create a thread/topic for your case in the T-replacement forum and keep using that so your case is not fractured across multiple threads.

Starvation can increase T4-->rT3 and that slows down your metabolism, a good survival strategy for surviving a food dearth.
