Sleep reset have you tried it?

We have an 8month old. He slept absolutely fine until the 4 month sleep regression. We have seemed to have gotten into a habbit of cuddling him to sleep which I love the snuggles however it is causing him to wake every 2 hrs over night and between 30-40mins during the day naps because he is looking for that help to drift back off/connect cycles. When he does wake up and we pick him up he drifts back off straight away and then it starts again every 2hrs at night and every 30-45mins during the day. We have now decided to do drowsy but awake at the beginning of all naps and night sleep so he is learning to drift off by himself. I have read that if you do a sleep reset where you gently rouse them 15m before their usual wake it can help them to connect the cycle by not fully waking and after a few days of doing this and the independent start to sleep they should stop waking. Had anyone tried it? Does it actually work?
