Just be patient and you will shortly receive some comments to your problem from MM. His comments are usually very thought-provoking. They may be for example: use less gas and thus save natural resources; develop friendship with any of the gas cylinder stockist; keep an electric oven at home as a standby; have a brick oven constructed at home where you could burn wood, scrap, paper and other trash material; eat at restaurants when you run out of gas ... etc.
