Adrenaline has no withdrawal effects, but often the energy spent as a result of the fight-or-flight response can cause the tiring. However, because adrenaline increases blood flow to skeletal muscle, other organs may have impaired functioning for a period of time, but it probably isn't enough to cause any long-term impairments.
"The elation you feel when you laugh is a great way of combating the physical effects of stress. When we laugh, our body relaxes and endorphins, which are natural painkillers, are released into the blood stream."
Actually adrenaline is a hormone that is secreted directly from the pancreas into the blood stream to the target organ, the liver and since there is no selectively permeable membrane it must be passive transport (diffusion).
The previous answer was wrong, adrenaline does not travel in the blood stream as it is an excepion to the usual hormones secreted from the endocrine system.
The hypothalamus is the main contol center of the autonomic nervous system, and when adrenaline, also called epinephrine is needed, it sends a neural message to the adrenal medulla so it can be released quickly into the blood stream, and since it is a vasoconstrictor, your blood pressure goes up quite rapidly preparing your body for the alarm response which is part of the flight or flight mechanism; part of the sympathetic division of the autonomic system.
hemoglobin
The adrenal glands secrete adrenaline which enters the blood stream, and is carried by the blood to the heart.
Adrenaline (epinephrine) is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for fight or flight.
Yes.

carbohdyrates
Yes when overly excited or surprised, your body releases adrenaline into your blood stream, witch causes perspiration, and possibly at a fast rate.
Yes. Adrenaline tells your liver to raise your blood sugar.
The human body uses the blood stream as a delivery system for chemicals. In the flight or fight response mechanics of fear, adrenaline is delivered via the blood stream to provide strength or endurance for egress or attack. The accelerated heart rate helps to deliever adrenaline quickly to needed areas, as well as increases the oxygen delivery to muscles, also aiding in egress or attack.
