Does a large amount of caffiene help in early mornings?

Less likely. 1. One need to find out why one so sleepy in morning and underlying cause needs to be evaluated and treated. 2. Drinking large amount of coffee/caffeine in morningon daily basis is not good, in moderation may be taken. 3. Inadequate sleep time for less than 7-8 hrs, , sleep interruption, sleep apnea, drug side effect, restless leg syndrome, delayed sleep phase syndrome are some common causes.
Yes. Certainly will help you wake up and be energetic for the day. I need my 2 cups. Caffeine has many beneficial properties such as anti-inflammatory and anti-oxidant. Many recent data to support this.
