Yea 4 days in a row probably a bit much. If you need something similar to Phenibut you should try Phenylpiracetam with a bit of Modafinil, or Phenyl + Faso. These combos seem to give the same stimulating quality of Phenibut minus euphoria. and since your taking low doses you're probably not getting any euphoria anyways. Take these on your in between days.
