@lamb I've temporarily stopped thyroid 3 times. Never gotten sick or really had any long term negative effects. If you want to do it, I recommend:
- Switch to T3 only 2 weeks before stopping, then taper off over a day or two.
- Stop in the summer when your weather forecast is sunny for the next few days
- Have lots of coffee and/or caffeine ready if you want to remain productive
- Take aspirin
You will feel pretty low energy for a couple days. Expect your lactate threshold to be very low. Do slow breathing exercises if you have difficulty sleeping.
