Im 26 weeks today but had horrible nausea in the beginning, I lost 20 pounds in 6 weeks. Ginger ale helped a little bit but lemons by far helped the most. I would drink iced tea with tons of fresh lemon juice. As far as back pain, I didnt have it that early but I get excruciating back pain now that radiates throughout my ribcage into my upper stomach, I take a hot bath with lemon verbena epsom salts which help with pain and relaxing then lay down. I decided about 2weeks ago to get a gel memory foam mattress topper and it was the best decision ive made. It helps sooo much. :)
Peppermints help with nausea. Body pillows help too.
For Sleep... I Started Sleeping With A Body Pillow. For NausEa... For Whatever Reason The Ice Breakers With Fruit On One Side Help.
