Tolerance Break Stomach Pain

I have been eating gummies to help me sleep for about 2 years now. I didn't notice until the other day I haven't had a tolerance break except once for a couple days. So I decided to do a tolerance break and start two days ago.

Yesterday I started having a lot of stomach pain and no appetite and the runs like crazy. I thought I had a 24hour stomach bug but I'm starting to think it's withdraw. It was so bad last night with randomly crying. I had a lot of stomach pain, nausea with no vomiting, restless legs, and chills. Im pretty sure I'm going through withdraw (which I guess me being naive thought that couldn't happen). I want to quit cold turkey. Do you guys have any suggestions. I did some research but wanted to ask as well. Thank you in advance.
