nausea and vomiting

Currently 7 weeks and 3 days with my rainbow. Wondering at what week you ladies started feeling sick and nauseous, and what week did you all start feeling better? 
My last pregnancy I was sooo sick and on meds for vomiting 3 weeks-20 weeks all day and night...thankfully it is very different this time around but still feeling shitty 😩.
Any thing you have found that really helps with the nausea and vomiting? 
Thank you for your replies! Wishing you all a happy and healthy pregnancy 🤰
