Beer
One row per beer size or strength.
Beer starts with one default row. Expand this section to change the count, size, or beer style.
Night-out calculator
Build the night in simple drink rows. Add each beer, wine, or spirit as its own line, mix and match freely, then see the combined alcohol load, calorie drag, water loss, roughness risk, and body timeline.
Example: 1 light beer + 1 craft / strong beer + 1 glass of dry white / rose + 2 US vodka shots.
Input parameters
Keep each beer, wine, or spirit choice in its own row so the mixed-night totals stay readable. Expand only the sections you want to edit, then the combined details update instantly below.

Beer-only night
1 beer of US Pint at Standard-Strength (~5% ABV)
Estimated clearance window
1 hr 52 min
1 beer of US Pint at Standard-Strength (~5% ABV) lands at about 18.7 g of pure alcohol, or 1.3 US standard drinks.
On the selected Man model, the current sleep band is Moderate night load, and water loss is about 187 ml. Use the replacement target below to top back up.

Drink breakdown
Each beer, wine, and spirit row stays separate, so it is easy to understand what each choice is adding before the totals are combined.
1 beer across 1 beer row.
0 wine pours across 0 wine rows.
0 spirit pours across 0 spirit rows.
Collective read
Only the beer rows are active here, so the total-night alcohol, calorie, carb, and fluid math comes entirely from the selected beer pours.[1][2][3][5][14][15]
No wine- or spirit-specific roughness multipliers are in play here, so the feel of the night is driven mostly by total alcohol dose.

Body timeline
The timeline follows the combined alcohol load from all active beer, wine, and spirit rows, so you can see how the full mix changes the night over time.
What you may notice
You may feel warmer, looser, or sleepier fairly quickly while the drinks are still being absorbed.
What your body is doing
Beer is still climbing in the bloodstream and sedation can show up before full clearance catches up.
Sleep terms in plain English
Alcohol can make you feel sleepier at first, then push REM later and leave the second half of the night lighter, choppier, and less refreshing. The mixed-night model uses total alcohol to set the base sleep band, then notes when rougher drink types are in the mix.[8][9][10][11]
Current band
14 g to 28 g of pure alcohol across the full mix.
This is where the first half of the night can feel sedated, then the second half gets noticeably choppier.
No wine- or spirit-specific roughness multipliers are in play here, so the feel of the night is driven mostly by total alcohol dose.

Clearance and sleep band[6][7][8][9][10]
The mixed-night sleep band is driven by total pure alcohol across every active row. Spirit roughness can make the night feel heavier, but the base sleep band still starts with the total alcohol dose.
