Clean.

Hello, I have been clean off Benadryl for about 6 to 7 months now which I am very happy for throughout that time of being clean I had a few cravings, mostly the first three months. Ever since I have not had a craving since. But recently, not too long ago, I had a craving It was very random even though I did not have a thought of Benadryl. Now today again I have the same craving and I don’t know if I can resist myself and not taking it. Why is this happening all of a sudden?
