any tips?

i want to try and have a WILD when i first go to bed.
i have asked around and i know it is easier during WBTB but i have also heard it is possible to do it when you first go to sleep. when i try to WILD first off i get the hallucinations that a few have mentioned (short of breath and thumping heart beats)
last night i tried this and the problem i came across was thinking about my techniques and trying to overcome the short of breath, the short of breath lasted for ages so i was aware it was a hallucination and i wasn't going to stop breathing, so i just kept going but it distracted me from my techniques which caused me just to fall asleep.

can you let me know if you have done this and any tips.

again i know its easier to do it during WBTB as ive done it, now i want at least 1 when first go to bed.
