My first attempt with Reishi lasted exactly 14 days. I took a 1000mg hot water extract capsule every morning, felt absolutely nothing, concluded it was snake oil, and moved on. Classic mistake.
Six months later, a friend whose judgment I trust told me she had been taking Reishi for three months and that her chronic insomnia had improved significantly. When I told her I had tried it and it did nothing, she asked how long I had taken it. Two weeks. She laughed and said that is not even close to enough time.
So I committed to eight weeks this time, tracking my sleep with a smartwatch for objective data.
Weeks 1-2: Nothing, again. Sleep metrics identical to baseline. Starting to feel like I was doing the same experiment twice.
Week 3: First signs. Average time to fall asleep decreased from 28 minutes to 22 minutes. Deep sleep percentage increased from 15% to 18%. Small numbers, but the trend was consistent across the week.
Week 4: Time to fall asleep: 18 minutes average. Deep sleep: 21%. I also noticed something my watch could not measure — I was feeling more rested in the morning. Not dramatically different, just... better.
Weeks 5-8: The improvements plateaued at a new baseline. Average sleep latency settled around 15-17 minutes (down from 28). Deep sleep percentage stabilized at 20-22% (up from 15%). I was also catching myself being less irritable in stressful situations at work.
The lesson I want to share: Reishi is not caffeine. It is not melatonin. It is not a drug that you take and feel an hour later. It is a slow, cumulative remodeling of your immune and nervous systems that takes weeks to manifest. If you bail after two weeks, you have not actually tried Reishi — you have just wasted two weeks of capsules. Commit to at least six weeks before making a judgment.
