I’m going to go out on a limb here and say - don’t do it … after lunch
I’m seeing an association with tinnitus and the amount I consume, including alcohol.
Just my ten cents but I believe it is possible that symptoms could be related to GERD or a GERD-like mechanism (even just stomach gases) irritating the ET.
The last thing you ought to be doing imho is over-consuming e.g. drinking with food and then lying down too soon with at least full-ish stomach.
Drinking with food is generally not a great plan, unless the food is very dry, as you can over-fill your stomach which makes acid reflux more likely and can make it harder to digest food.
I’ve found fasting between a late lunch and breakfast reduces my tinnitus (which is a proxy for all my other symptoms I used to have).
Interesting GERD has come up a lot on this forum. I wonder if this is just a co-incidence …
