Intensity of morning sickness varies widely. My wife was fortunate and was never too bad. You might be the same. OTOH - it can be quite severe for some folks. Take the time you need - that's what sick time is for!!!

It varies from person to person and pregnancy to pregnancy. I do think eating well helps make it less bad. Luckily I never threw up and never missed work. I did have a few miserable days when the A/C wasn't working where the heat combined with mild morning sickness made me miserable. Stay cool. That helps.
