In a scale from 1 (the weakest) to 10 (the strongest), I would rate is as 3.
However, I do not think that the thirst was the issue of any importance.
What my family started to observe, a day or two before they "convinced" me to cease my dry fast, was my personality change; I was told that I became a short-tempered, despotic and harsh manner absolute ruler. Frankly saying, I did not notice anything.
What I did notice was something else - the feeling that something was pulling me somewhere. Today I hardly feel it.
In conclusion, I am glad that my family intervened and rescued both me and our yearly canoe adventure.
