28th day of 60 day water fast!

Today is my 28th day of an complete water fast. I'm very tired, weak, and annoyed. I can smell everything!!! Omg it's really crazy. And each smell makes me feel extremely nauseous. The smell thing is by far the most difficult thing I have encountered while on the water fast. I do not know what to do. I can't eat. My stomach is so upset. I drink a gallon of water each day. And sometimes I squeeze a lemon and add salt for taste and it also help with the upset stomach. I also have a sweet taste in my mouth. My plain distilled water tastes sweet. That is very bad as well. I hate the taste. I have lost 40 pounds and I seriously look like a different person which is why I cannot quit. I have to continue. These last few days have been so hard. The smell thing is driving me nuts. I usually go to the gym for an hour or two. But lately I have not gone to the gym because the smell makes me want to vomit. Any advice would be helpful. Any!!!!
