A 30-year-old male asked:

will a week off of caffeine reset my body's tolerance?

Tolerance to what?: I must assume that you mean the effects of caffeine on your heart. By abstaining from coffee or tea or any other food that contains caffeine, the effects should definitely be gone in a week. That should also apply to any stomach or urinary problem or sleeplessness effect of the caffeine.
Dr. Robert Grindstaff
Addiction Medicine 38 years experience
Caffeine : The caffeine should be out of your system in 1 week but you may experience headache or increased headache due to the caffeine withdrawal the tolerance you may have aquired maw take longer to disappear

Pinky toe: Although it may not be structurally the most "fragile" bone in the body, the most often broken bone in the body is the 5th (or pinky) toe. In some sports, like sailing, the pinky toe is broken in 50% of athletes who are involved in the sport for more than 2 years.

Does your body get used to the fitness if you run every night?

Yes!: You will accommodate and will not have to work as hard so you will not get as good of a workout. I am a big advocate of hiit (high intensity interval training) and recommend you add hill work or some sprints to your workout to challenge yourself - 30 sec sprint with 90 sec jog works well x 8. This workout also enhances natural secretion of growth hormone and increases your resting metabolism.

All depends: 1) do you take narcotics regularly? Your system will metabolize more rapidly. 2) are you asking how long they will provide effect? Typically 4-6 hours. 3) are you asking how long will it be before you test negative on a urine drug screen? Probably 2-3 days.

How long will pseudoephedrine last in your body?

1 doctor answer2 doctors weighed in
Dr. Thomas Benda, jr
ENT and Head and Neck Surgery 34 years experience
Depends on dosage: The bottles are usually labelled as to how long they last. 60 mg is marketed to last 4 to 6 hours, 120 mg 12 hours, and 240 mg all day. The generics may not work as a sustained release tablet as well as brand name drugs here. Pseudophedrine can cause palpitations, jitteriness, insomnia, and high blood pressure. By about age 40 i tell most people not to take it with any regularity.
