recommend avoid fluorenol
Obtained a sample of fluorenol and tried it in hopes that it would be more effective, less expensive, and less hepatotoxic than the isomers and prodrug of modafinil. Bought into the hype. Wish I hadn't. Recommend sticking with molecules more closely associated with modafinil. They are much better understood, proven to work, and safer.
Used various doses of fluorenol, ranging from a couple hundred milligrams to a couple grams. Wakefulness did not improve. Generally felt worse -- tired, fatigued, worn out. Memory registration and long-term recall both tanked. Also had several episodes of sleep walking (likely a drug-drug interaction). In recordings, appeared awake, performed complex tasks, and had intelligible conversations.
During the fluorenol trial period, did not use caffeine (not even decaf). Did not use modafinil (or closely related substances). Did use baclofen, citalopram, and zolpidem. Baclofen use was minimal. Toward end of citalopram dosing cycle, occasionally have SSRI withdrawal symptoms, which tend to worsen with increased sleep debt. They did not significantly change during the trial period.
Daily zolpidem use was consistent with usage prior to the trial period. Although zolpidem is known to cause complex sleep-related behaviors, the only reports of any unusual nighttime activities was during the trial period. Prior to that, had no unintended effects during years of use. The sleep-walking was likely induced by zolpidem after cognitive function was first impaired by fluorenol.
After the trial period, have tried several isolated doses of fluorenol with similar effects. Each time, wakefulness did not improve, felt generally fatigued, and memory was impaired. Sleep walking did not recur. Perhaps the permissive effect of fluorenol on zolpidem does not occur until after several days of continuous use. Improved sleep duration and quality does not mitigate the negative effects of fluorenol.
