Prepare for both the possibility of being overwhelmed and under-whelmed. Many people report not getting what they expected but still becoming 'addicted' to the experience. A suspension can be a life changing experience in that the individual will be attaining a feat that, to many, might seem impossible. Then again, you might just hang from hooks.It is an extraordinary experience to be suspended, and once you are back on the ground you will be high from the experience. This can last anywhere from a day or two to a week, but at some point there is the coming down and it is inevitable that this will happen. For many, an awakening may have occurred and when you come down from the initial high you may be out of sync with a reality that was opened while suspending versus the reality we all share. There are no grave dangers afterwards when performed in the right settings and if you find yourself feeling really down after suspending it would be wise to share your feelings with others experienced in suspension.
Finally, it should be noted that due to the complexity and somewhat overwhelming task of interpreting the experience, you may not feel the spiritual or psychological effect until weeks afterwards when it hits you like a ton of bricks. In addition, understand that the normal rules of time may not apply -- don't be surprised when if a fifteen second suspension gives you what seems like hours and hours of experience to interpret.
