Hi Maggie66C,
I don't have the salt taste, but I do have a fairly constant tingling on the tip of my tongue. I also notice that it frequently feels like I've burned the roof of my mouth & my tongue without any known cause. This has been happening for about the last month (the tingling has been coming on for several months).
I have heard of others with taste issues, though. I'm sorry to hear you are dealing with this.
Cheryl
