How did your morning sickness hit you?

Hey ladies! 
So for those who have/had morning sickness...did it come on gradually for you or hit you like a ton of bricks? I'm currently just over 5 weeks. I've been feeling symptom free...until last night...& my head hurts so bad, almost like sinus pressure, I feel weak, running to the bathroom, so nauseas but not throwing up. I'm panicking because next Saturday we move and are flying from Hawaii to Denver , road tripping Denver to Arkansas. Staying with family and driving to Cali a month after to move into our new home. I feel like I'm never going to make it 😭😭😭 any and all remedies you ladies have please share!
