i was diagnosed with hypothyroidism (hashimoto's)about 1.5 years ago. i went on synthroid and then about 5 months ago decided to go off it and try natural methods to bring it back into balance. my memory was poor during the time that it wasn't regulated, however now it is better. i would suggest that you have the following tests done to determine how severe your condition is (check your free t3, free t4 and tsh levels). you have to ask your doctor to so all of these otherwise s/he will not. if they are abnormal, then you can either go on synthroid OR you can try some natural remedies such as T100X and an adrenal support. these can be purchased at the health food store. The natural remedies take longer to take effect (be patient) but they work since i just regulated my thyroid NATURALLY using them. good luck- if you have any questions, feel free to email me.
