Can't sleep!!!!

Victoria
I'm 5 weeks and already I feel nauseas all the time, I pee loads but most annoying thing of all is this insomnia 🙈 it's driving me mad! Every night I wake up around 3 and can't get back to sleep till 6 (if I even manage that) then I'm up at 7! 
I work 2 jobs and can't afford to be tired! Anyone know any way to keep me a sleep? 😂
