It's too solid. Id advise you to wait till day 4 with this kinda food. go with a very diluted tomato juice.
Something like this:
1st day: very diluted juice. First two hrs: every 30 min 1-2 tablespoons
After this: every hour 1/3 cup
Day 2: tomato juice every 1.5-2 hrs
Day 3: add a little bit of boiled tomatoes to every "meal"
Day 4: what you suggested for day 1, small portions
