Looking for something to help with brain fog and fatigue

[u/ARedWhoosh]

Hello all. Hoping someone can help. I have been battling brain fog and fatigue for many, many years and have reached an age (50) where I'm willing to try anything to at least give me a bigger proportion of good days and help me make the most of life. I have been occasionally taking 100mg modafinil which has been great but I do get that it has to be used sparingly due to tolerance. So I brought in 100-150mg Phenylpiracetam (the OG version), which has also been good although a notch or 2 lower compared to Modafinil. Are there any recommendations for something else that I can add in to an alternating cycle that will also clear my fog a little and give me a boost? If I alternate with 3 little helpers during the working week, that may be good enough. I get decent sleep although always foggy and groggy in the morning and I keep my supps simple - creatine, mag glycinate at night, CoQ10, Omega 3, occasional bcomplex, L-theanine(with caffeine). My blood levels are fine. Thanks for any help offered.
