Hi Krinkle, welcome to PC!

Do you have other parts or is it like you are wondering if the person you are when blitzed would be considered an other part?

Alcohol lowers all inhibitions, and if a person has walls up on their behavior- whether real or imagined, when drinking, those walls come crashing down and a person will behave differently... that doesn't mean a person has "alters", it's more like a sober person/drunk person thing.

The more a person drinks, the more a person's thinking and decision making is affected causing one to behave differently and to do things that they normally wouldn't do.

Switching alters generally doesn't take alcohol to happen, but it can be a trigger for some. Switching occurs when dissociation is triggered to happen, something (anything trauma related) a person's mind tries to avoid associating with which leaves room for an other part to become to fill in the void and handle what caused the dissociation in the first place. DID/OSDD is a lifelong living condition since early childhood caused by a trauma related incident.

If you feel that this is a possibility, only a specialist dealing with trauma related memories can sufficiently diagnose and treat you. I hope this helps.
