Most of that looks to be SLUDGE symptoms which is what you go through for nerve gas before it kills you. I imagine that there is a difference in severity there but that would then support that SLUDGE to a more minor degree is what you might start getting after tension headaches.
Sarin: Biological effects
The short- and long-term symptoms experienced by those affected included:
* difficulty breathing
* disturbed sleep and nightmares
* extreme sensitivity to light
* foaming at the mouth
* high fevers
* influenza-like symptoms
* loss of consciousness
* loss of memory
* loss of bowel control
* nausea and vomiting
* post-traumatic stress disorder
* respiratory problems
* uncontrollable trembling
* vision problems, both temporary and permanent
Convulsions, breathing difficulty, loss of bowel control, paralysis, respiratory problems, and uncontrollable trembling all seem related to the fact that acetyl-choline is the neurotransmitter for muscles and disturbing that wrecks muscle control. I would assume trembling, clenching, cramping and weakness to be possible milder version of that then. Memory loss and other mental problems stem from its role in memory which make sense too. In the case of nerve gases like sarin, death usually occurs from asphyxiation which occurs do to the inability to control the diaphragm, a muscles.
Looking at MrSpud's list and this one gastrointestinal disturbances seem to be likely too at some point.
