I don't think it's an unreasonable demand that you want to be able to have regular appointments -- I'd be a big pouty baby too if scheduling was always such a problem! That would drive me nuts! I think just try to be straightforward, calm and assertive about it, and tell your T that you feel it's important for your progress to see him more often, that you want to keep a sense of momentum going - and ask to discuss any possible options. Maybe consider the first slots of the day as well as the last? Only you know what's workable for you -- but that's just it, it has to work for you! Hope you figure something out
