If you filled it and it was OK for a while and now it is acting up again it sounds like you have a leak and you really need to fix it instead of constantly refilling the system. Have the system pressure tested, find and fix all leaks, drain and refill the compressor with fresh oil, and maybe replace the accumulater/dryer. Replace the service valve cores. Have the shop pull a hard vacuum and hold it for at least an hour before recharging. Also make sure the condensor coil is clean, that is, it is not plugged up with leaves and debris and that both fans are working, blowing in the right direction (front to back) the fans are tight on the shafts, the circuit breaker for the fans is uprated so it isn't cutting out, and the cooling system for the motor is in good shape. The A/C is tested with the inside fan on high speed and the motor should be running over 1000 RPM. The A/C cannot be properly tested for performance at idle.
