Hello! I am somewhat new to Stata and have tried to find an answer to this on other threads but have been unable to find something that works with my dataset. I have attached a snippet from my dataset. I have upwards to 6,000 observations, so you could see why I am trying to find a way to code for this issue.

This is a dietary recall dataset. I am trying to begin data cleaning, and one of my parameters is that I only want to include subjects that have recalls from two days (as opposed to only one). I am having trouble coming up with a way where I can ultimately create a variable and code it 0/1 for if they have recalls for two days or not. As you can see, the number of entries for each ID can vary greatly. Some have 6 while others have up to 14. This obviously doesn't matter when I just need to verify that I have recalls for two days, but it does make it a little tricky to handle since I can't reshape the data. Can someone lend some insight on how to handle this? I am open to hearing other suggestions that may be better than what I'm trying to do as well.

I appreciate any and all help I can get with this.
