Side affects of taking Valerian root and papaya & pineapple enzymes?

I have been taking the two for a while now, what would be the side affects of taking these (both recommended dose) say 5 times a week?
Papaya & pineapple enzymes contains bromelain, papain, mycozyme. I like to take it after dinner to help digest.
and Valerian root with passion flower, which helps me sleep (albeit not too help)
And bad side effects?
