Finally sleeping through the night
Chronic insomniac for 12 years. Tried everything from melatonin to prescription sleep aids. DSIP is the first thing that consistently puts me into deep, restorative sleep without that groggy morning feeling. By night 3 I was sleeping 7-8 hours straight. Life changing.
Deep sleep stages dramatically increased
My Oura ring data tells the story. Before DSIP I was averaging 35 minutes of deep sleep. After 2 weeks I was consistently hitting 70-90 minutes. The difference in how I feel during the day is profound. Cognitive function, mood, energy, all improved.
Reduced my cortisol levels
High stress job was keeping my cortisol elevated even at night. Sleep was terrible and I was wired but tired. DSIP helped break the cycle. After 3 weeks my nighttime cortisol levels dropped according to a salivary test. Sleep quality followed.
No more sleep aids needed
Was dependent on Ambien for 4 years. Tapered off while introducing DSIP and the transition was far smoother than I expected. 6 weeks in and I am sleeping naturally without any pharmaceutical sleep aids. Feel more refreshed in the morning too.
