It is so funny. Until I read your post and the replies, I didn't make the connection whatsoever to Adderall. My mouth doesn't feel raw necessarily, but it does feel as if I've got cotton mouth and I have to constantly drink something. I've only been taking 20mg of XR for a little over a month, so I just chalked it up to the summer heat.
My issue with Adderall so far is how it is affecting my sleep. I've always been one who can't seem to "turn my brain off" at night, so I have the TV on. Pre-Adderall, I would eventually fall asleep and stay that way. Now, not only do I have trouble getting to sleep (I was up until 6:30am last night/this morning), but if I do get to sleep and wake up even for a second, I can't get back to sleep.
I'm curious to see what others have to say about the dry mouth issue, so thanks for the posting!
