"After spending all day on a client's project, it's tough to get enough momentum on my own stuff."

"How hard would it be to maintain a 30 to 40 hour client workload"

One thing that I learned early on (which forced me to sell my first company before pursuing another opportunity) was that you have much more time than you have energy. Which is essentially what you are saying. The distractions of day to day things takes away from creativity and drive.

On the plus side you will be in a completely new environment which I think is essential to even having a chance of making this work. The fact that the school is essentially full time 4 days a week will allow you to work the other 3 days, say 10 hours per day. So that is the decision you have to make. Do you feel you can work 7 days a week for the time period of the program.

Keep in mind though that once you have completed the program you will still have to find the time to keep up your skills in whatever you have learned and you will still have the pressing needs of your current customers as well as the handcuffs of the income that they provide. That's going to be difficult to transition off of in my opinion.
