"i have to agree with the other reviewer who described less aggressiveness when taking tramadol. i was originally prescribed this for back pain, but have come to desire it more for its mood altering capabilities. it&#039;s stated that this product has a &quot;very weak but rapidly acting serotonin-norepinephrine reuptake inhibitor.&quot; i&#039;ve noticed that i no longer throw tantrums and that i&#039;m in general a much calmer individual. i do however wonder what the price is in the long run in terms of dependency."
