I just recently started upping my dosage of levothroxine from 25 mcg to 50 mcg. My body does fine on 25 mcg except for me being tired always and being kind of dizzy. But I had just recently started taking 50 mcg of levo and it seems like my tongue swells up a bit more than usual at night and towards the morning time. A long with me feeling shaky, and making it hard for me to sleep. Has anyone else had these problems when upping a dosage? And did you keep taking the higher dosage? If so did the scalloped tongue and sleeplessness subside in time?
