Hi I have gone through your query and felt that the side effects of drugs are toubling you with sleeplessness and lack of appetite . I suggest you to drink 1 and 1/2kg or more of lukewarm water at a stretch stand near the wash basin , shake your tommy and vomit it whole of water you drank . It will detoxify your system giving you feel of recovery . Then you take 2-3 glasses of warm water with lemon with little salt every half an hour . your health will come back soon.you will feel hungery Take light fibrous food wheat porriage ,fruit - papaya ,apple, pears ,oranges and veges , soups . Live healthy , balanced life style , regular sleep , diet and exercise , Take some hobbies of reading , playing painting or anything of your choice to be engrossed in some worth while job ,in your free time . select your friends who can help you to be away from addiction If you feel any further urge of addiction , contact a psychologist around you Hope this helps you in solving your query .Take care .All the best Dont hesitate to come back if have any further query .
