I would suggest you contact your Doctor as it may make your levels unstable.....probably causing hyperthyroidism.
Its best to be on the safe side.
Normally if I am a little hypo, I will eat 2 small cans of tuna (iodine in it) and it stops the hypo symptoms somewhat... (little trick there for those whose TSH is up a fraction , hehehe).
Seriously though,,,,ask your Doc.
