Headaches are quite common while detoxing. An epsom salt bath in the evening could be really helpful – add a drop of good quality lavender essential oil and it will help to calm your system down before sleep too.
Also be sure that you are drinking enough water to keep that flushing action going.
If it gets to be too much, consider eating something from the backup foods list.
