Narrative:
Just after rotation; stick shaker activated and continued until landing back at hnl. We had a previous problem with a window heat light flickering on takeoff -- was written up and had just been MEL'ed. Captain was flying and continued to do so. There was no pertinent checklist to run but we did reach up to just cycle the stall warning switch. Stall warning indicator disk was spinning. We did not look for a popped circuit breaker. No time and safety of flight during critical phase of flight was more important. We concentrated on maintaining proper flight path and profile and returned for landing. Captain stated that aircraft control was difficult with stick shaker activated. We did not declare an emergency or request any special handling. We took off from and returned to runway 4R and remained on tower frequency.
