I feel like you are doing something wrong. My Pharmaceutical Lab is still level 3 but I do make about 250k in Alcohol daily plus I have a storage that saveguards about 150k of alcohol so I can get the required alcohol in about 3 days.

But again don't go for attacking others to get loot unless you get some huge loot because your Army also costs you Alcohol and Weapons so sometimes you may end of losing more than you get.

So if you have low production rate of Weapons and Alcohol you might want to upgrade those.
