My Problem With Ssild

I had been trying SSILD for a while now,the 2 times I actually did it right were both lucid,the problem keeping me away from lucid dreaming is that after I wake up 5 hours after i sleep,is that as soon as i start the "vision sensing" I barely reach 7 seconds without falling asleep,is there anyway to stop this?

Everyone is different; therefore the technique should be adjusted to suit each individual. In your case it seems that you need to wake up a bit more before returning to bed to carry out the cycles.
