RE: spring fever
No cure is known by modern medicine at this time.
One's only realistic hope is to manage the symptoms as best one can.
Some useful techniques for effective management of the fever flare ups include breath control -- deep, slow, rythmic inhalations through the nose and exhaling through the mouth when you feel the shakes start. This can be repeated often through the day with no ill effects other than possible hyperventilation and dizziness if the breaths are not slow enough. It is possible that your boss and co-workers will notice, so descretion is the key in a work-place practice of the technique. This technique can be done with eyes open or closed. Most people afflicted with more advanced and chronic symptoms prefer the closed-eyes technique, since it allows for more variations of mind imaging (such as imagining a relaxing day in a hammock between palm trees on a quiet, white-sand southern Pacific beach with gently rolling torquoise breakers washing up on shore).
It is best to stay away from forums such as this. In spite of the short-term positive sensations and comfort associated with a "fix" of this nature, it actually exaccerbates the problem by intensifying the long-term need for more and more such "fixes."
The best mid to long term cure is to have repeated failures and frustrations every day throughout the actual turkey season, such as henned-up gobblers, hush mouth toms, other hunters ruining your hunts, hung-up longspurs, terrible weather, too many coyotes, and other such irritants and general negative experiences which you can easily associate with the affliction itself.
Another effective long-term treatment is to develop a wife that puts her foot down and demands more attention be given to her with an ultimatum that forces sanity on your part.
Good luck!
