Hi Satya, Welcome to HealthcareMagic Forum.
You are suffering from Prescription Drug Abuse
. You should be seeing your Doctor immediately. You will require counseling for this, don't try to stop it by yourself else it may be detrimental to your Physical and Mental Health. It is not a heavier dose though and it has to be tapered gradually and stopped finally. Speak to your Doctor.
Wish you Good Health, Take Care.
