Kendra,

My neuro said exactly the same thing as Kate's!

I am allowed to take a dose early (like 30 min. early) if I'm active and 'running out' - - but they're really encouraging me to try to stick to a four hour schedule. I am allowed to take 1/2 doses if I'm doing really well. But they seem to prefer that I keep the intervals contant while allowing me some discretion with the dosages.
