Whether or not that is OK is another matter but I do not feel that I suffer from doing so.
There is interaction with coffee if taken near each other (impaired absorption) - but I am not convinced the story would have been any different with tea, hot chocolate or anything else than water!
My Dr and pharmacist told me it was the calcium carbonate in milk that affects the absorption of thyroxine, so I don't think it's the caffeine. There are other things that affect the absorption too like Fibre, antacids, etc which is why the suggest taking it on an empty stomach with water!
Good luck finishing your PhD! I remember how tough the last few months of my PhD were.
