Wow...weve been GOOD Red...we have a star! lol
There is a lot to the mechanics between the thyroid and the adrenals. Maybe in your case you had a remission of the Hashimoto's. Hashi's tends to go in cycles of hyper then hypo. It may just well be that you felt ok enough to not take your medication and felt ok afterwards.
The ONLY way to know for sure if you are having adrenal problems is to have your cortisol levels checked through out the day. Not many doctors are going to be in on that one!
There are other diseases that can cause the issues you are discussing. I would encourage you to have a full evaluation by your doctor.
What you mention makes sense, getting up early, etc. But after time the body sees this as an extra stressor that is not usual to it, and it may last a few months but it can start to fail. Believe me, I have tried what you are saying and found it to work for a few months then I start to crash.
You are right that adrenals need to be addressed for thyroid function to work, but often there is underlying causes for this not to happen. These need to be investigated.
Thats not always the case with thyroid issues.
The adrenals DONT fire up the thyroid if you have Graves Disease...the antibodies do.
I cannot comment on Hashimoto's but in the case of Graves, it is the antibodies that fires up the thyroid and not the Pit. Gland or the Adrenals.
