13 days on erfa thyroid and last 2 days have felt awful: sickly, dizzy, headache, lethargic, a little depressed. On the bright side seem to have balanced my bp and temperature . Is this normal for some people? I don't know what to expect - if I thought it would settle down then I would persevere. At moment I feel worse than on Levo. Had a good moan so will finish post!
