I was going to say the same about tylenol and it being bad on the liver. I am not sure how safe benedryl is long term either. There is obviously a difference between people who have an occasional night with sleep issues who take these and like many here who have chronic sleep issues. I have tried so many meds for sleep and am really struggling with it still. What about an anti anxiety med that can aid with sleep too? I understand the gi upset. This morning I was so nauseas. Do you take your meds with food? I do even my night time ones I take with a snack. It helps to a degree. Sorry I am not much help. Sending thoughts
