Frequently Asked Questions

Is DSIP like a sleeping pill?
No, it's not sedating like traditional sleep aids. It promotes natural deep sleep architecture without grogginess.
How long until I notice effects?
Some feel effects the first night, but optimal benefits often develop over 1-2 weeks of consistent use.
Can I use it every night?
Research suggests it can be used regularly, but many cycle it (5 days on, 2 off) to maintain effectiveness.
