Definitely bring what YOU feel that you'll need while in the hospital. I know that when I went I had NOTHING. It was awful not even to have shampoo. I had to use regular soap until my friends sent me a "care" package. Bring "regular" clothes because most Beh. Health Units allow clients to wear their own clothes.

A lot of units don't allow cell phones, computers or ipads/androids pads. I think that's pretty limiting, but there is no way around it. You might want to check with the unit you're considering. I had to make phone calls to family and friends from a phone in the cafeteria. Needless to say, there was NO privacy and that was difficult.

Good luck and I hope the experience is helpful and is what you are seeking!
