Gaurav: If your need is for some medicines which are required to be sent to you regularly from India, then I suggest you stay back in your country. It appears that possibly the condition of your health will not allow you bear the demands of the job and the ways things move here in Qatar. They are far different from the coziness of your home- life in your country. At times they are very demanding.
As for your query, there is a post that has appeared at QL just some minutes back which may answer your question.
