Most of us begin to feel the effects of the Zeez Sleep Pebble within a few days. For some people, it can take six weeks to experience differences. You may take less time to fall asleep, wake less often, sleep longer, and feel more rested. What really matters is how you feel during the day. If the quality of your sleep has improved you will feel better.

No. The radiated power of the Zeez Sleep Pebble is too low for any measurable current to cross the skull into the brain. There is no induced field passing through the brain (unlike Trans-cranial Magnetic Stimulation) and no current stimulates the brain (as in Direct Cranial Stimulation). We believe that it has a resonant effect – and that our brain responds to the pulses rather than being directly affected by them.

The Zeez Sleep Pebble is fully safety tested to UK, US and EU standards, and is safe for people of all ages, including those with a pacemaker. Don’t use it if you have untreated sleep apnoea - our body’s need to breathe will take precedence over our need to sleep deeply. Once sleep apnoea is treated, the Zeez Sleep Pebble can be very useful.

We think that people with epilepsy should avoid using the Zeez Sleep Pebble.

The Zeez Sleep Pebble may not be effective for people who have two or more joint replacements, and its efficacy is likely to be reduced for people who are taking benzodiazipines, and may be reduced if we take medicines that reduce absorption of vitamin D and magnesium.

Yes. Many people have used the Zeez Sleep Pebble alongside medications such as zopiclone, zolpidem, amitriptyline, trazadone, Lunesta, Ambien, CBD oil, and melatonin. Most have gradually tapered off their other medication.

Can medication affect the efficacy of the Zeez Sleep Pebble?

Yes. Benzodiazepines and certain drugs for the treatment of bipolar disorder affect neuronal activity. The Zeez Sleep devices may have little effect when lithium is used and less effect if Xanax, Valium, or diazepam are used regularly. Some peopel have used the Zeez's alpha frequencies during the dayt to support them to reduce benzodiazepines before sucessfully using the Zeez Sleep Pebble to help sleep. In such cases achieving good sleep may take longer than for those using other sleep medications. Contact us if you want to know more.

Drugs that reduce stomach acidity affects the absorption of nutrients and useful supplemewnts such as Vitamain D and magnesium. This in turm can affect the efficacy of the Zeez. Ths solution may be to increase supplements and eat a nutrient dense diet.
