Effect of Alprazolam SR (XANAX XR)

I took alprazolam SR (sustained release) 0.5 mg for the past 3 days. In these, three days, I did not take any multivitamin or any other drug or nutraceuticals. Also, for the past one week, I did not take any multivitamin formulations.

Positive effects:

• Reduced anxiety
• Able to concentrate on work and stay focused on work
• Generally good mood

Negative effects:

• Excessive sleepiness especially after lunch
• Loudness of voice was low
• Stuttering was there  - unable to complete the sentence - lack of breath control

Mechanism:
Probably increased dopaminergic neurotransmission and increased glutamate neurotransmission.
