Here is a manga that I've found called KUU GA UE KARA SHITSUREI SHIMASU. From what I've learned it is a monthly series about a short girl who wants to be taller. She drinks an ungodly amount of milk and it causes her to grow into a full blown giantess. The rest of the series chronicles her trying to have a normal life and the silliness that it brings.
Below is a link to the series however there are two problems. The first that it only has chapters 8-14 and 1-7 are missing. The second is that it is in Japanese. So far I haven't found it in English at all.
