When does the witching hour end!?

LO is 4 months + 5 days and still screams bloody murder from when she wakes up from her last nap (between 5 and 6p) until bedtime at 7:30. She’s changed, fed (many times) and burped and she still screams. It’s been like this since the first few weeks. Tried had drops and gripe water with no success. It’s so exhausting to listen to, dinner is so unpleasant and I have to eat with a screaming child in my arms. What has been others experience? Is there a light at the end of the tunnel?
