You'll never be able to go deep SAFELY without cleaning out first. Here's one method you can use.
Coffee enemas are EXTREMELY good for you. They detoxify your liver and clean you out very well PLUS, you don't feel tired afterwards. Here is the procedure:
Brew 4 scoops to one full pot of coffee (usually holds 2 quarts) of an organic or low acidic blend, Starbucks "Veranda" blend works quite nicely **DO NOT THROW OUT THE GROUNDS!**. Let it cool or add some ice cubes if you want it to cool quickly.
While it's cooling, add one tablespoon of Baking Soda and one tablespoon of Salt. Mix it well and then pour half of the pot (one quart) into your enema bag. Take it slowly and hold it for at least 20 mins.
Once you're done expelling, get up and re-brew the old grounds with another full pot. Once the pot is done brewing the second pot of coffee (which will look VERY weak) bring it upstairs and expel the tiny last bit of gunk that you had form the first enema.
Now take the last quart of the first brew and hold that for 20 mins. It should be much easier the second time around as you have already gotten rind of a lot of crud in your system.
Once you have completely finished the second quart, go onto taking the full 2 quarts of the second batch of coffee, again, make sure to add one tablespoon of baking soda and one tablespoon of salt.
During the entire procedure you should drink at least one bottle of Gatorade to replenish your electrolytes.
Once you are done insert a but plug to stimulate your ass into releasing the last little bits and then enjoy a nice clean ass without the tired feeling of having done a deep enema session.
Good luck and hit me up if you have any questions.
