try combining the techniques into one big routine, do WBTB, WILD, RC's, etc. Your mind will be so stuck on LDs your bound to have them. combining them all probably ups your chances by 20-30x. i use to be very strict doing all of those and i'd commonly have LDs 4-5 nights of the week, sometimes having around 3 in a night. whatever you do, don't give up on it... because that's when you fall in a rut and starting over sucks.
