Make sure its in gear, turn bars to full lock on whatever side its fallen onto. i.e. if it fallen onto its left side, put full left lock on. Turn away from bike so your bum is resting on the edge of the seat, bend knees & take hold of bars with right hand and suitably sturdy part of rear end within grasp of left hand (obviously vica-versa if its on its right side), then just start to lift whilst walking backwards.
Sounds complicated but it works & is generally a bit safer for your back.
