Valium can cause anterograde amnesia (an inability to recall the recent past), which may persist as long as 6 months and may not ever fully return to normal after an individual stops taking the drug.
Percocet addicted individuals will eventually find that they need to use the drug to feel normal, and will exhibit drug-seeking behavior and often become preoccupied with thoughts about using and obtaining the drug.
Symptoms that are typical of antidepressant withdrawal include flu-like symptoms, insomnia, nausea, imbalance and sensory disturbances.
The abuse potential of Morphine is among the highest when compared to other analgesics which are available and in use to treat chronic pain.
