Question

Dear Sir or Madam

I am writing to let you know that i currently have had some sign of having insomnia. Therefore, i usually being of no attention and cannot remember things in detail.

Let me explain my own problems. The trouble started about 2 months ago when i accidently saw the advertisement of coffee, my cup of tea, i definitely bought and took a fancy of its flavour. I drank amount to five cups a day and couldnot stop doing this. As such, i have not been able to sleep properly and therefore cannot concentrate on my work as well as be affected my memory.

I would be greatful if you tell me about the methods you use on the course and the cost of its and the date it starts.

I look forward to your reply.

Yours faithfully.
