hey guys, I'm having a problem and would really appreciate help on this one.

I decided to give lucid dreaming another go after starting a DJ earlier but dropping it quickly last year.
now I am highly motivated after watching 'lucid dreaming - gateway to the inner by Robert waggoner' on youtube,
bought a dream journal and started in on Friday last week.

worth mentioning is also I meditate 2 hours a day, every day.

the problem:
as soon as I decided I wanted to lucid dream and remember my dreams, the first night I woke up 4 times during the night, immidiatly after a dream,
remembering some parts of it. the last few nights since then have been the same. I of course started to wake completely every time I would wake up with memories to write them down in my DJ, the thing is since I'm doing that I'm exhausted during the day due to not being able to sleep through the night I think. Anyone has an idea what this problem is caused by? (I assumed at one point that I might actually get lucid but then wake without remembering it, would that be an option)

also I would like to hear a recommendation on how to proceed, should I continue to write everything down in the middle of the night when I wake or should I leave it and wrote down what I still have in mind in the morning?

I really appreciate help, thanks a lot already for reading.
cheers
