I am used to downloading heavily and this addiction started with a love for music and good movies groomed by by schooling in unilorin where i use 3 lecturer passwords to download in cis.
sorry if you don't know
after leaving school things have not been the same till recently.

for Internet in nigeria I use glo 1k for normal browsing
and sometimes night plan on mtn and airtel. glo because it is slow and will last

There I write out in a book what I want to download. and subscribe for ntel night plan for 1.5k that gives me unlimited from 10-5am to download all I want.
plus I have a blog.

oddverbs..com

dedicated as a solace for weirdos
and with it I download at least 50-60 gb per month.
The only pinch is you have to buy a mifi which goes for 12-14k after that it's download galore

I hope you find this useful.

p.s. let's share knowledge nigeria. It only gets old
