I had trouble sleeping for my first month after wards but I found that tea helps me so much. I drink the brand sleepy time, and I get their "extra" tea bags. It honestly works like a charm for me. It may be a placebo by now but the act of getting into bed with my hot tea and drinking it gets my body ready for bed and helps me stay asleep up to 8 hours.

This obviously may not work for serious sleep conditions but it helped me get past my bed night time anxiety.
