the 555IC
fahime, looking at your schematic you have the relay directly connected to 0V and 9V to the other side from pin 3..... in the standby state the 555 pin 3 will be high (+9V) and pull in the relay , this may be what you mean when you say it's still drawing current. the "trick" you are talking about could be changing the polarity to the relay coil, in other words, from pin 3 connect one side of the relay and from the other side of the relay connect it direct to +9V, basically you will now be triggering when pin 3 goes low (0V) because in the other state you will have +9V on each side of the relay coil and it will not draw current until your switch triggers the IC, lemme know if thats what you were referring to.....Good Luck , I kinda had the same problem on another project until I realized pin 3 was high all the time (when not triggered) so I swapped the leads and it worked perfect.
