What's worked for me... making sure I have my vitamins.

Something that sounds so minor has a major impact on how I handle things.

Without vitamins, after about three days of low-carbing, I get irritable, weepy, feel always about to snap at someone - not good at all.

With vitamins, no problems at all. But it did take a long time to figure out the correct dosage for me.

Potassium: 3-4x day
Magnesium: 2x day

Give it a shot - within a day, you should really notice a difference (magnesium hits within a couple of hours).

Hope whatever you do works for you =0)
