Lufenuron made me feel like a new person for about 10 days and then I started to get bad die-off syptoms for about 3 weeks after that. I heard the lufenuron can stay in your intestines for 2-4 weeks. The die-off was too much for me to work and take care of 2 kids at the same time so I only did one treatment out of Sarah Vaughter's three pack. I really need about 2-3 months off work to hammer this crap. So I'm pretty limited right now on gaining the upper hand, but I can only battle this crap for so long and might have to take some serious time off work to gain some good ground. The problem is you get the battle from trying to reduce the candida in numbers and then trying to restablish the gut ecosystem and then trying to detox your body from chemicals/toxins/metals. It can be a hard battle especially when one has to work and take care of 2 ankle biters(toddlers).
