First off have you been taking the vitamin B drops every day? Also besides the PS1000 drops and B drops are you taking ANY other supplements? Any changes like adding in any foods you have never eaten before?
I think with this stuff it is process of elimination. Also are you drinking a lot of caffeine? Any? Or have you recently stopped drinking caffeine all together?
What I would do for now is to quit the B drops and just see how that affects your cramps. Also if they are causing you this much discomfort and pain I would highly suggest visiting your doctor!
Let me know if this helps…if not we can dig a little deeper.
