I had some trouble sleeping last night, but I’m not sure how much of that was from the M2. I had very vivid dreams, and woke up more than once with wood. If the wood gets worse, I can see how it could be difficult to sleep.
I did take valerian root and melatonin before bed, which can give vivid dreams, but it’s not unusual for me to take those. Once, I woke up from a dream and saw a lingering visual pattern that I’ve only ever seen before on salvia. So, I don’t know what to make of it.
