When you "drink" you drink betweeen 3 and 10 units of liquid. If you just want to drink 1 unit, use "sip":
Code:
if (subcmd == SCMD_DRINK) {
char buf[MAX_STRING_LENGTH];
snprintf(buf, sizeof(buf), "$n drinks %s from $p.", drinks[GET_OBJ_VAL(temp, 2)]);
act(buf, TRUE, ch, temp, 0, TO_ROOM);
send_to_char(ch, "You drink the %s.\r\n", drinks[GET_OBJ_VAL(temp, 2)]);
if (drink_aff[GET_OBJ_VAL(temp, 2)][DRUNK] > 0)
amount = (25 - GET_COND(ch, THIRST)) / drink_aff[GET_OBJ_VAL(temp, 2)][DRUNK];
else
amount = rand_number(3, 10);
} else {
act("$n sips from $p.", TRUE, ch, temp, 0, TO_ROOM);
send_to_char(ch, "It tastes like %s.\r\n", drinks[GET_OBJ_VAL(temp, 2)]);
amount = 1;
}
