Hare Krishna.

Is there a book that could tell me details on foods to avoid as krishna devotee and also the prayers and routine to be followed every day?

I understand that we should avoid onion and garlic apart from eggs and meat. But i would like to know about other ingredients if any?

I also would like to know about foods to avoid on Ekadashi and when to break fast. I read somewhere that you always break fast on the following day and should be awake the whole night of ekadashi? is it true??

Little guidance would be very helpful.

Jai Gauranga Jai Nitai!!
