Dry spells SUCK. I had a teeny tiny short Ld last night but it was also going on three weeks for me. Also a recall dry spell with sometimes just one fragment remembered, where my average is about 4 scenes per waking.
What I did to shake things up:
Joined the competition, added motivation, watched some motivational videos on YouTube (sports themed but still highly relevant)
Shook up my bedtime intention mantras, changed them around and get good recal again 2 nights ago, then pretty good again last night plus the really short lucid (but hey lucid is lucid).

I'm very similar to Op, SSILd tends to really wake me up, but I did it last night while simultaneously doing my get-back-to-sleep relaxation ritual. I very quickly got body hallucinations but they subsided, anyway did get back to sleep and did get that little lucid, so progress.

You just need to find ways to keep things fresh, mix things up sometimes. Reading the dream journals of advanced LDers really helps with motivation.
