The effects of alcohol can vary significantly from person to person, depending on factors such as weight, metabolism, tolerance, and individual differences. In the case of a 17-year-old girl weighing 110lbs, consuming 2-3 shots of vodka could potentially lead to intoxication due to her lower body weight and potentially lower tolerance compared to larger and older individuals.
Keep in mind that underage drinking is illegal in many places and can have serious consequences, both legally and for health and safety.
Regarding memory while intoxicated, alcohol can impair memory formation and lead to blackouts, where a person may not remember events that occurred while they were drunk. Blackouts occur when alcohol affects the hippocampus, the region of the brain responsible for forming new memories. The more a person drinks in a short period, the more likely they are to experience memory gaps during intoxication.
It is essential to remember that alcohol consumption should be done responsibly and in accordance with the laws and regulations of your location. If you have concerns about alcohol use or its effects on memory, it's best to consult a healthcare professional who can provide personalized advice.
