Mild to moderate fevers are not bad for the body though and medicine to reduce fever, when taken in excess is harmful in the long run. Fevers are not pleasant, but they don't kill (mild or moderate level). Same with nightmares. It's coping mechanism, not something to be done away with immediatelly, imho.

Treating symptoms (or bodily coping mechanisms) as if they were the disease is not gonna help in the long run.

And trauma should be dealt, first and foremoremost, in therapy or simmilar process. You can do it totally without meds and imho, it's preferable way. Too much stuff in you can interfere with your processing stuff, especially the downers.
