Make it alive!
You are definitively using too much powder and not enough water.
Before using the probiotics, warm up some milk (1/2 liter) to a human body temperature, add one spoon of probiotics powder to it, mix it, and let it stay overnight inside preheated thermos, to keep the temperature as long as possible.
Wrap the thermos into a blanket or pillows.
The next day you should have a nice, live, yogurt with millions of billions times more live bacteria than what you started with in the evening.
The live bacteria should actually double its number and its volume almost every 60-180 seconds.
Blend that yogurt with clean water (human body temperature) so it is not too thick, and use at least 1/4 liter of it as enema, and try to keep the liquid inside for at least 1-2 hours or even longer (whole night or whole day) if possible.
That is how to implant real live bacteria into your colon.
The number of bacteria you would get this way should be millions of billions times more than what you would get from the dry, half dead, powder you started with.
