Urge to yawn when trying to engage SP?

[JeffGerlitz]

When's the best time to relax/mediate and try and let SP start/takeover? I usually fall asleep on my back with my hands on my sides. The few times I've had SP sensations has always been in this position. However lately I haven't been experiencing any (over 2 years) last night I tried relaxing and keeping myind awake and leaving my body still. The only interruptions I was getting was a strong urge to swallow and an occasional itch that would almost become unbearable. I realize scratching the itch would kill the whole attempt...but what about swallowing? I would assume your body swallows for itself even after your in SP uncounciously..or am I wrong on this? Is it better to practice this right when you get in bed....or in the middle of the night? If you experience SP sensations alot can you please tell me your routine before you go to bed? What do you drink before bed, do you stretch? Do you listen to music? How do you keep your mind awake (counting, visualizing)? How long does it normally take before the sensations usually begin? Thanks
