There could be something to this. I am aware of false temporal awareness in memories whereby people think something happened a week ago, when it was 3 months ago, for example. But, if this effect on one’s memory is common, it certainly isn’t remarkably so, nor it is disabling– a bit of a nuisance, perhaps. But, it is noteworthy and one should be aware of this potential. The good news is, anecdotally, that these effects fade with abstinence.
