In what ways can you become immune to the sickened condition before 20th level?

[Chaosvii7]

I wanted to play a Bloodmage, which has a class feature that sickens you if you if you have too much arcane magic welled up inside of your blood. It does not ignore immunity to sickness, so I have been looking for ways to get myself immune to sickness, and I can't seem to find any.

Does anyone have any suggestions?

Take the Strong Stomach feat (Cityscape).

Can you give me a source on Bloodmage? Only one I'm finding is DanDWiki, which means it's most likely bad homebrew.

Anything which gives you a Construct or Undead type cancels sickness, like Necropolitan, Warforged, or Half-Golem.

I assume that he's talking about the Pathfinder class, which can be found on that system's SRD here (http://www.d20pfsrd.com/classes/prestige-classes/other-paizo/a-b/bloatmage).

Air Races from UA (partial immunity) - don't have to breathe air and are therefore immune to most causes of the sickened state

Warforged. Immune to a lot of stuff that flesh is heir to, as they possess no flesh.
