Coffee and Caffeine FAQ

On the positive side for NoDoz you do get a measured dosage.
On the negative side NoDoz is a fairly strong does of caffeine at 200 mg per pill. That’s the equivalent of a very strong cup of coffee. That is the smaller problem the larger issue is that where coffee, tea and other beverages are a relatively slow release due to their volume NoDoz will hit you all at once. The food recommended in the previous comment will help this.
Personally I still recommend going with cutting back slowly on whatever you have been drinking/eating to this point.
