Hi, was wondering if anyone knew the equivalance of 162 Synthoid to NP
thyroid ? Synthroid or elevated T3 is causing my nervous condition. Past few day's, upon waking I'm fine, I take synthroid approx 2 hours later, the nervous condition kicks in. I've taken Synthroid for past 9 months, no problems till approx 3 weeks ago. Trying to figure out what's causing jittery conditon. My whole body constantly shaking, after a few hours calms down, I get headache, then exhausted.
