Nausea, Nausea & More Nausea

I am 12w4d and I am one of those unlucky ones who has been super sick the first trimester. I was losing weight, constant nausea and vomiting and wasn't eating enough. Around week 9, I was put on Diclegis- which don't get me wrong has done wonders- however, I have gotten sick several times even while on the medicine. This past week, I have been getting sick again in the mornings and now my nausea is terrible at night! I haven't had nausea at night up to the point... 

Anyone else experience this? When does it go away? I'm so sick and tired and feeling sick and tired 😷😷
