A master's degree should take around two years to earn, during which time you'll complete between 30 and 50 hours of coursework and finish a written thesis that is likely based on original research of some kind. At the end of your program, you'll probably have to pass written or oral examinations as well.
Ibuprofen is a phenylpropionic acid NSAID introduced into the United States in 1974 as a prescription product intended to treat arthritic conditions at daily doses of up to 2400 mg. It was subsequently approved for daily doses of up to 3200 mg/day, and then as a prescription drug to treat mild to moderate pain in 1978.
Probably best to stick to the recommended dosing on the bottle though. For adults, that's 400-800mg four times a day (Maximum 3200mg/day US labelling or 2400mg/day Canadian labelling) Dosing for children is weight based. If your symptoms persist for more than 24 hours with ibuprofen, you should probably see your physician rather than keep taking the drug. Unless you are allergic to it, or have gastric issues such as ulcers or gastritis. Or have kidney disease, or advanced liver disease, or heart disease, or late in pregnancy.
