Well, personally i use them to get SR wildcard rewards on the Daily missions, when i see i have like 7/10 and it's like 1:45 AM (at my place Dailies restart at 2:00 AM) OR i use them when it's also time for me to go to bed, and i miss just a few EXP points to get a new level-up, to not let the Refill boxus Stamina and Focus get wasted.
For example: i currently have liek 300 STA Max, so half-pudding gives me like 150 STA. Which means, roughly, 150 Exp points if i roll something like Exploratrion Missions, which give you teh same emount of Exp per Sta usage (i.e. 1Sta=1Exp there, while, for example, on Girl Hunt Quest it's 15 Exp for 20 Sta, so, 2 Sta=1,5 Exp there, and on gambits and other stuff the rate is even lower).
So, if i have, say, 4,850/5,000 Exp to the next level, am at 0 Sta and is going to bed very soon, i just use a half-pudding, to get those 150 Sta for those last 150 Exp i miss to get the level-up, getting that level-up (while advancing on the Exploration Missions, gaining points and ranking on Events or just completing some extra daily missions for Gifts, for example, or finish my currently unfinished Exp, Pero or Chance Time Dailies), then use up all the new Sta i got from the level-up and go to bed. Otherwise i'd just woke up with 300 Sta next day, and get a level-up while still having like 150 Sta, losing it and the extra Sta i could get instead of those during a level-up.
So i get the best of level-ups this way (and i also usually try to use my Focus before getting a level-up, too) and have like 20 Peronamin and like 40 Peronamin-Half all the time stashed for the Dark Hour. =)

Also, keep in mind that during Events you get Temporary Consumables, like Bloody Mary/BM-Half and Pumpkin Pie/PP-Half or Pero Shakes/PS-Half and PeroBurgers/PB-Half and so on, which will, usually, disappear from your inventory after the end of each given Event, or at the beginning of the next one, so make sure you use them up before the current Event ends (helps alot to gain EP and Rank during last 2 days of event for me) or at least, feed them to Kurito in the Items Menu, so you get at least something for them instead of just losing those items.
