I recall 2 years ago, I tried to increase my lemon juice intake since I really liked the taste and the cleansing feeling. I took only half of what you are taking and it took about 10- 14 days, but I vomited about 3 or 4 times at bedtime. I vomited lots of stomach mucous and I believe it was a good thing, but vomiting is unpleasant so I reduced the lemon and was fine. My stomach was better for it though. Writing this now, I am considering to try the increase in lemon again for the cleansing stomach reaction, though I would cut it back after vomiting.
