Using plain water enemas for a length of time plus only feeling completely empty after an enema made me think that you were dehydrated. Since you weight only 102 lbs then half your weight is 51 lbs This converted to your required water consumption is 51 oz, which is approximately 6 glasses of water.
Don’t even think about SWF time being instead take, when you feel plugged up, a 2 quart baking soda enema. This will flush you out and also alkalize you. One more item to remember to get regular BMs is that you need lubrication. You need daily to drink or use in cooking or in salad dressing at least 2 tablespoons of good oil. I use extra virgin olive oil in all my cooking and also in my salad dressing.
If you want to do a cleanse before you are completely regular (2/3 BMs per day) you could go on a 3 day juice fast as described in my blog. I strongly believe that going on several short juice fast (3/5 days) can accomplish pretty much what other cleanse claim.
I hope that this answers your questions but if you need more info please don’t hesitate to ask. I will try to answer all your questions.
