Coffee is good for you

Totally agree.

Started taking tea after dinner (other than my usual intake during the day) for few months couple of years back, started suffering from insomnia and other health issues (mental and physical), was prescribed anti anxiety medication, sleeping pills and some other medication for physical health.

Most of the times, people's health issues are due to the fact that they themselves mess up their body's natural chemicals with the intake of these toxins not knowing if they suit them.

Every body reacts differently to different toxins. If you have a very strong and robust physical health, you might not even notice the difference but people with sensitive system should limit their intake of coffee as per their own body's acceptance level or requirement of the toxin. Excceeding that would definitely mess up their system.
