Judy - you can do it. It is about change, habit & tastebuds.
I changed the type of coffee I bought so that it didn't taste the like the same old coffee...with a weird white substance in it.
I went stronger with an expresso blend and put quite a bit of SILK in it to get the creaminess.
So I was drinking a brand new drink - not my old drink changed.
Try changing tea brands, make it weaker or stronger so it's a complete change and not you giving something up.
You will adjust quickly! You probably won't enjoy the first couple of cups but you'll adjust and your body will accept it quicker then you think :)
I applaud you and anyone else who is making a step forward in the right direction.
I don't miss anything I've given up now - many of my long time past favourites actually make my stomach turn now.
