medication or remedies for badd morning sickness!!

Genny • baby #2 his #1 due 4/8/16

My friend is 12 weeks and though I am happy we r pregnant she has terrible ms and haven't been to work since becoming pregnant. Problem is where we live doctors only prescribe gravol for ms but she doesn't like it cause she is always drowsy

can anyone give a non precipitation drug or natural remedies for relief please so I can pass it to her??
