OK - it IS late but I am now starting to understand the Datasheet - I am switching into an Idle state, not a sleep by using
Code:
             OSCCON.7 = 1     'Set IDLEN - switch to SEC_IDLE
if I use
Code:
             OSCCON.7 = 0     'Clear IDLEN - switch to SLEEP
the PIC goes to sleep but wont wake up on Timer 1 interrupt. The consumption does drop to 15 mA.
Help please!!! How can I get Timer 1 to wake the Pic from sleep?

I am going to sleep now - hope my Timer 1 wakes me! My anaesthetist friends tell it is easy to put someone to sleep - the skill is in getting them to wake up afterwards - guess that is true of Pics too!
