Sensations you got are a good sign of you getting close. Sensations and types of entry into WILD.

If you get excited and sensations and HH stop, just calm yourself down and keep going. You should get them back in no time.

If you are excited as you lay down to WILD (after WBTB) and that keeps you awake, try telling yourself that you not gonna WILD, you just going to sleep as usual. As you get sleepy and closer to falling asleep, start your mantras and whatever else you do for a WILD.

Keep trying. Sometimes HH can get entertaining and almost as good as LD itself. It's worth your time trying, you will get it soon, no worries.
