Hello there....getting ready to do my 2nd flush tomorrow. I did not get any stones out on first round and I believe it was due to not being able to fall asleep. I've heard about ornithine and melatonin, however neither of these do anything to help with my insomnia. The only thing that works for me is a sleep-aid, which has an antihistimine as the main ingredient. My question is.....is there any harm in taking this antihistimine with the olive oil mixture right before bed? Has anyone else tried this? Will it prevent stones from releasing? I would appreciate anyone who has had experience with this or knows any info.
