My gf had her thyroid removed when she was young. She's now 35 and has been taking thyroid medication daily. She neglected to have her levels checked for quite some time and now her levels are low. Her doctor just increased her dose from 100mcg to 112mcg. Her energy levels have been depressingly low. My question is how long will it take for the new dose to effect her so that her energy levels return to normal. The doc says she is gonna retest her in 6 wks. Also is the 12 mcg even enough of a bump to really make that much difference? She would rather be in the hyper rather than hypo end of the spectrum if possible. What dosages do you all recommend typically? Thanks
