If someone is in alcohol withdrawal, vs tend to go up, they'll feel anxious, nauseous, tremulous, and sweaty as the time since their last drink passes. If it's benzo withdrawal, they'll probably get a huge headache and some numbness/tingling in the extremities along with the above symptoms.
In opiate withdrawal, the pulse increases, and the same nausea, tremors, and sweats are common. In addition, the pupils tend to be huge, the body aches feel like the flu so the pt can't sit still, and the nose and eyes water. You might see excessive yawning and the cravings are nearly unbearable to use again just to feel normal.
I'm amazed at the number of pt's that abuse prescription drugs. It catches them so unaware...after all...their doctor PRESCRIBED them. They just needed A FEW extra.
These drugs are illegal, too. Right?
