Extreme fatigue

Im currently 7w+3d with my second. I'm so freaking tired... I can't even eat because the Exhaustion takes over and id rather sleep then eat. I haven't been able to finish a whole meal on a week- when I do actually finish a meal it's taking over an hour (something simple like a PB&J; with apple slices) I'm sleeping through the night, at least 8-10 hours and taking naps with my minion. I rest most of the day because of being so tired. Is there anything I can do to maybe help combat the extreme fatigue? Even if it's just enough so I can eat.

-Coffee isn't an option, it taste disgusting at this point.
