It sounds like your cat has a tapeworm. Using a home remedy has the potential to cause more harm to your cat than waiting until you can take him to a vet. Tapeworms are debilitating in only a minor way, unless the cat is very young/old or has other medical problems, or has several worms. So, I'd advise waiting for the vet's treatment. It won't cost much and is very effective. Your biggest headache, since you live in a rural area and ?let your cat outside, is that you have to deal with the flea problem that created the tapeworm problem. Unless you keep your cat flea-free, the chances are that he will swallow another tapeworm infected flea and start the process again.
