Since taking Synthroid for about a month now, I have had a strange taste in my mouth. It's not a bad taste and not really a 'taste' as much as a sensation. It's like I chewed some mint gum recently, kind of that residual 'cool' feeling. Has anyone had this sensation in relation to Synthroid or hypo? It's just enough to bother me and concern me that there may be something else wrong??? Thanks.
