Hi and welcome! I am a many time, long time cleanser. I live in Mexico where lemons are hard to come by, so virtually always use limes, which are yummy and very supportive!
It is not by the book, and there are arguments against, but my nutritionist/naturopath says there is no problem with the cayenne caps and I have fasted long term many times with caps very successfully. The cayenne is a very important addition to this cleanse as it cuts mucous like a White Tornado! Excess mucous is a bad guy and must be removed! Definitely give cayenne a try.
You did a good thing falling back to a cleansing diet before trying again. I ate fruits/vegs for 30 days before my 60 day fast last summer with multiple benefits! Before a ten day I like to eat this way for about a week. If you are a big coffee drinker, sugarholic etc., the detox can be heck that first week! Coffee is famous for the type of headache you describe. Ouch!!
Sounds like you are a prime candidate for a good cleanse! Let us know if we can help you in any way to reach your goal.
Best,
Somer
