I'm 33 weeks and still vomiting like no tomorrow. You're very lucky
It is normal this early. I had my only real morning sickness at 7 weeks, where vomiting occured. Now I am 8.5 weeks and feel fine. If possible eat a lite,healthy snack just before you get out of bed. Like a few mixed nuts or crackers that you can keep on your night stand. Don't forget plenty of water. But yes you are lucky as am I.
I got my nausea that was all day from 8 weeks till about 16 weeks.
I never had morning sickness .. I'd feel nausea but never get sick .. The dizzy spells could be blood pressure dropping or sugar levels or the baby's blood flow
