I was the same introducing even allowed things such as Kefir and Buckwheat.
I thought to myself on both times that I can only set myself back a couple of days so I went for it.
I know this is rich coming from me, but key is moderation.
Have 2-3 bites one day and watch for a reaction. No reaction have 2-3 more bites the next day and see how you get on.
Any reaction stop and wait a few more weeks.
