This has been a concern for me too. I have been on maybe two dates since my band. I am not really interested in dating a whole lot right now because I am very focused on my own health and the changes I am making within myself, but being young and single, dates are bound to pop up from time to time. The first date I went on I ordered a small meal and just made sure to take a lot of time to converse in between bites so I did not end up throwing up in the bathroom. The second date, I decided to make it so it was not focused around food, so I went for tea and a walk on the beach. I honestly would not have a problem letting somebody know on the first date if it came up, but I don't think it would be something I would just throw out there if the opportunity did not arise. I am not ashamed of it at all, I actually have gotten very comfortable talking about it with people. I think if I were to go on a date with anyone who half sparked my interest it would be something important for me to get out because it is such a big part of my life right now. Anyways, just sharing my thoughts on it.
