Used sparingly caffeine is usually a safe stimulant and makes for great-tasting coffee; used in excess it can create a range of dizzying side effects, including death. For many people 300 mg of caffeine a day is an acceptable level but for others it is not. Note that caffeine levels vary in coffee, tea and drinks. A Starbucks coffee for instance would range from 10 mg to 415 mg. For someone sensitive to caffeine, it is unwise to consume reckless amounts of the stimulant without first consulting an expert on the matter.
Caffeine overdose symptoms
Symptoms vary from person to person, but most extreme users of caffeine report an accelerated heartbeat, confusion and anxiety. Some have difficulty sleeping and have night terrors; others have headaches and feel jittery, feverish, dizzy, thirsty, irritable, and suffer from shortness of breath. The stimulant is so powerful that 10,000 mg can end the life of a human being weighing about 150 pounds. If you are sensitive to caffeine, consuming even 200 mg a day is too much and not advisable for you. Have your levels tested and speak to an expert on the matter whether the stimulant is safe for you.
