If Pliny is to believed the book was referred to as De sua ebrietate (On his drunkenness), no excerpts survive afaik.

But it is not to be wondered at that Cicero was desirous in this respect to eclipse the fame of M. Antonius, the murderer of his father; a man who had, before the time of the younger Cicero, shown himself so extremely anxious to maintain the superiority in this kind of qualification, that he had even gone so far as to publish a book upon the subject of his own drunkenness. Daring in this work to speak in his own defence, he has proved very satisfactorily, to lay thinking, how many were the evils he had inflicted upon the world through this same vice of drunkenness. It was but a short time before the battle of Actium that he vomited forth this book of his, from which we have no great difficulty in coming to the conclusion, that drunk as lie already was with the blood of his fellow-citizens, the only result was that he thirsted for it all the more. For, in fact, such is the infallible characteristic of drunkenness, the more a person is in the habit of drinking, the more eager he is for drink; and the remark of the Scythian ambassador is as true as it is well known—the more the Parthians drank, the thirstier they were for it.

(translation by Bostock & Riley)

sed nimirum hanc gloriam auferre Cicero voluit interfectori patris sui M. Antonio. is enim ante eum avidissime adprehenderat hanc palmam edito etiam volumine de sua ebrietate, quo patrocinari sibi ausus adprobavit plane, ut equidem arbitror, quanta mala per temulentiam terrarum orbi intulisset. exiguo tempore ante proelium Actiacum id volumen evomuit, quo facile intellegatur ebrius iam sanguine civium et tanta magis eum sitiens. namque et haec necessitas vitium comitatur, ut bibendi consuetudo augeat aviditatem, tanto magis sitire Parthos.
