Hi,
About a year back, I went for a full checkup. I had put on weight and I
used to feel tired. I also had problems doing day to day work, like
while trying to tighten a screw, my hand would hurt because of the
effort I would put on it tryin to rotate the screwdrive.
At the checkup, I found out I had put on 20 pounds and had TSH levels
as high as 220. I also had cholestrol on the higher side and fatty
liver.
No one in my family has any history of thyroid problems.
The doctor didn't venture to offer an explanation on the high TSH
level. He put me on a dosage of 0.075 of levothyroxine. I also stopped
my "In and Out" burger binges and went on a healthier diet.
After a couple of months, my TSH levels came down to normal. My
cholestrol and fatty liver also came into normal ranges. And I was back
-20 pounds.
In the summer, I went into training for a 4 days hiking trip. After
discussing with my doctor, I increased the dosage to 0.088.
After coming back from the trip, I settled back into my old sedentary
lifestyle, but the dosage remained the same.
I started getting irritated over little things and feeling misearable.
After a TSH level check, I found I was really low, 0.02. So the doctor
gave me a new prescription for 0.05 mg.

I don't want to keep trying various dosages.
Neither my doctor nor any websites offer an explanation about any harm
that would befall me if I were to stop the medication. Everyone just
insists on taking the medication daily without fail.
What happens if I were to stop taking it? Would I revert back to my
earlier symptoms?
Maybe whatever dietary/behavioral reasons that caused the initial spike
are no longer applicable and my TSH levels will automatically come back
to normal if I were to leave it alone.
Please let me know your thoughts.
Thanks in advance.
