Hashi swings--please share your experience.

[Guest guest]

I have hashi's, but not on meds yet.

I will have several days where I feel great--plenty of energy, get

lots done, sleep well, positive mood.

Then I'll wake up one morning and feel dreadful--terrible fatigue,

heart pounding, migrating aches and pains, difficulty sleeping.

This will last a couple of days, them I'm back to feeling great again

for a few days, then I'm down again.

Does this sound like Hashi's or something else?
