afternoon nausea

Is anyone else suffering with horrendous nausea, particularly in the afternoon?? I'm 9w3d. Mine hits around 4pm and comes in waves, though have never actually thrown up, but constantly feel close 🤢 find its worse if I'm hungry, trying to stay hydrated but too much water seems to set me off! I've found the only real remedy is to sleep, but that's pretty impossible when you work full time!! Anyone got any remedies? (I'm UK)
