the fact that its just a nap basically whether or not you fail. it really kills time too if youre bored. i usually take 25 minutes to get to SP in the afternoon (havent tries it at night) and ill usually make 4to 5 attempts which is about a 2 hour nap. its cool because i get extra "sleep" in while trying to have an LD. its like multitasking while sleeping.... or something. when do you think its the best time to WILD? i havent tried WBTB yet. i think that might be more effective. can someone explain to me when the best time to WILD is?
