Its also really hard on the clutch and hydraulic components keeping the pedal pressed in the whole time you are at a stoplight. That may have something to do with your problems.
Do you keep your hand on the shifter all the time as well? Don't do that either, you can wear out the synchros and shift gates if you are applying pressure on the shifter without realizing it. Basically you should never touch the clutch pedal or shifter unless you are actually switching gears, or will be within the next few seconds.
