Can I still get loans?

[manders33068]

Alright guys... Here's my situation. After I graduate from a Ph.D program I will have about 100 grand in federal student loans... I have heard that there is a limit as to how much money the government will let you borrow before it cuts you off even if you are working towards a degree. I would like to stick with federal loans, but if I can't get any more federal loans for medical school, can I still get private loans and if so, do they have a limit and how bad are the interest rates?
Thanks for all your help!!
