I really cannot say if this product if effective of not.. BUT- side effects were instantly noticed. Prescribed dose of 100mg @ AM & PM. First dose: Wednesday night 100 mg; second dose Thursday morning, 100 mg. I didn't feel myself, thought it was from being tired. I began to realize that I didn't feel present. Continued taking medication, and continued to feel this way.. it is called depersonalization. I have felt spacey, as if I am just going through the motions. I am stopping this medication.
