Ummm, I'm not trying to intrude or hijack your thread. But please count yourself lucky! DD is 3 1/2 & refuses to be potty trained. Well, she has a kind of modified potty training schedule that she's designed herself.
She will always "do #2" in the potty, but other than that, she will only occasionally do anything else. Some people say that she just might not be ready, but if you knew her & her stubborn personality, you would know that she is refusing to use the potty b/c she knows its something that she can control & that it's something that drives me nuts! (She is extremely manipulative & is almost brilliant when it comes to "not" doing what you want her to.)
Sometimes, she'll yell for me to come to bathroom & say that she's going to pee, so I'll get all excited & try to encourage her & let her know how proud I am of her, etc., etc. Then she'll stand IN FRONT OF the toilet & pee in her panties!!!! Then she takes off her panties, throws them down & runs off laughing.

(Both of my boys were potty trained in a week - no problems at all - except at night, when we used pull ups.)
But, sometimes she'll go all day using the potty, so I don't know.
To address your OP, though, that does sound like a lot of liquid. That's one thing my mom pointed out to me. She thought that maybe she had to go too often b/c she drank so much juice & water. So far, cutting down on liquids hasn't worked extremely well for me (but, at this point I don't know what will....), but it's just something for you to think about.
I just wanted to let you know how jealous I was of you!
