Medical technician symptoms and conditions

I have had great experiences with Levothyroxine. I am no longer tired, achey, grumpy, constipated. I feel great. I am only 27 years old and got my hypothyroidism from having my first child. I am excited that my levels are now normal after 3 months (TSH was 25.89). I was on .50 mcg now I am on .75. Feel great!
I am a medical technician and have found that a lot of people who start on a certain medication for hypothyriodism, such as Synthroid - do not fair well if they have to switch. My doctor always says NOT to switch...not EVER. She repeats over and over again to check my prescription every time I receive it. That means checking the pills against each other, because hypothyroidism medication is one of the highest missed - filled prescription. If I were anyone who has had to switch, I would demand to be put back on your original meds. Have your physician write up your symptoms with the new meds and make a recommendation to the insurance company that you NEED synthriod.
