What position do you meditate?

I have meditated sitting in the comfy Lotus position, but with the Gateway i started doing it laying on my back. I feel its easier to get into F10 with mind awake and body sleep. My body get in to the sleep frozen state very rapidly while laying. When sitting it takes too long time and my neck gets exhausted. Is it just me or should it be possible sitting as well, how do you guys do this!
