Study 1 and Study 2: Mean and SEM TLFB drinking variables covering the 45 days before (T1) and 45 days after (T2) alcohol self-administration experiments for laboratory alcohol exposed participants and the corresponding time period for controls without experimental alcohol exposure (study 2).

	Alcohol-exposed (n=18)
	T1	T2
PDD	24.3 ± 2.8	25.7 ± 1.8
D/DD	6.3 ± 0.9	3.8 ± 0.6*
PHDD	13.1 ± 1.9	9.4 ± 2.2*

	T1	T2	T1	T2
PDD	31.1 ± 2.3	24.0 ± 2.2***	27.7 ± 2.7	21.2 ± 2.3***

^***: significantly different from T1 at p<001;

^*: significantly different from T1 at p<05.

PDD=percent drinking days; D/DD=drinks per drinking day; PHDD=percent heavy drinking days (≥ 4 drinks per day for women, ≥ 5 drinks per day for men).
