Hello: I have been taking levoxyl only for 2 weeks now, and i get dull headaches that pretty much last through out the day now... when i did some reading i realised that it was a migraine headache... i called my doctor .. she asked me to cut my dosage in half... but a couple of days later i still have the same symptoms.. so she asked me to stop it completely... and meet her up for an appt... will the side effects disappear once you stop taking levoxyl?
