The only way I can think of is to limit the number of waiver moves each team is allowed to make. This will place a premium on the moves that you do decide to make, and not let you make decisions on a whim, or just by a good game. This is especially important in a league where bench spots are scarce and teams are expecting to rotate their kickers/defenses in the waiver wires.
oh, and btw, u really should try and get ff access at home. it is definitely worth it and will probably make you more productive at work.
