TSH became low after medication

below are my tsh, free t4, free t3 at different dates. i started using synthroid 25 mcg from 9/10/2010 for 2 months. i should have not used for that tsh levels. my pcp at that time did not mention that i need to take medication for whole life time. after that i have been using homeopathy medicine - 1)thyroidinum 3x 4 tabs/day until 04/01/12, later 2 tabs/day 2) kalium phosphoricum 6x 4 tabs/day 3) acid phos 5 per month .but in latest test, tsh dropped down to 0.04 . i was surprised to see this. what should i do now? in 8 months, it reduced to 0.04 from 6.24. free t4 & free t3 are in normal range. my hair is falling. my skin is dry. i get dry flakes (mixed with red color) in nose daily. i changed my pcp now and i have appointment next week with new pcp.

1) is my thyroid affected badly
2)i feel like uncessarily my thyroid levels are disturned by taking synthroid and later on thyrodiunum though tsh was only 4.96 initially
3)if i stop these homeopathic medications now, will lmy tsh come to normal range
4)if it comes to nomrmal levels and if i do not take medication, will my tsh levels be normal
