It's complicated. Some people say you should swallow, because not swallowing distracts you. Other people say you mustn't swallow because it will, like you said, reset your timer to SP. I'm of the opinion that you shouldn't. You shouldn't move at all. I've tried propping pillows up so my head is elevated and I'm less likely to need to swallow, because laying on my side pretty much puts me to sleep.

The other people may be right too. They must have tried it out and found that they could still WILD even though they swallowed. I guess it just depends on what method you're using and your own personal style.
