Yes, the first trimester was horrible for me too - So much nausea and vomiting and sleeping. I was so grumpy and tired. This lasted for 18 weeks. Now I am 30 weeks and hoping it wont come back.
The only thing that helped was discovering what the triggers were for my nausea and avoiding them (for me, dairy products were triggers for the first 12 weeks - so used oat milk, and eating more than a tiny meal in the evening).
I would get from peckish to hungry-sick in 30 seconds, so I had to keep nibbling on boring things that didn’t make me sick to keep from being empty (potatoes and bananas I found were good, crackers didn’t work), or things that I was craving (sea weed, marmite).
I was also more nauseous in the evening, which meant that I could have a normal breakfast, a small’ish lunch and I knew that I would probably throw up my evening meal, so most of my nutritious meals were in the morning/lunch.
The tiredness was bad, but I just went to bed early (8pm). I was struggling with nausea anyway so being awake was just not pleasant.
I also found the Myrtle & Maude sweets helped a little during the times I was getting really bad (https://www.amazon.co.uk/gp/product/B0BDFJDW6B/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&th=1), they are basically mints with more B6 vitamins. I tried ginger but it just irritated my stomach.
However, this is all very individual. I hope you find what works for you! It is a real nightmare, but at least it gets better in most cases.
