I'm taking melatonin but analyze: what's the optimal supplement stack for MY sleep issues? Map the supplement categories: sleep pressure (magnesium), sleep maintenance (glycine), sleep latency (melatonin), anxiety (L-theanine). Calculate: based on my specific sleep problem, which supplements target it? Show me the stack hierarchy: take these first, add these if needed. Give me the dosing and timing: this supplement at this dose at this time. Include: what supplements help my specific issue vs. generic recommendations, proper dosing and timing, and whether I'm taking wrong supplements for my problem.
