That is possible by affecting the neurotransmitters Acetylcholine and Norepinephrine, both of which are boosted by Vitamin B, but nothing is guaranteed. Your best bet is to use a DMAE supplement (Vitamin-B agonist) right before your REM5 cycle, so wake up after 5-6 hours of sleep and take a moderate dose.
