It is likely that your body comes into a new alignment during the session. After the treatment you might feel minor aches or pains for a day or two as the body adjusts to the new position. Especially on the day of the treatment it helps to drink water and avoid caffeine. Soaking in a bath tub with Epsom salts can help you to integrate the aftereffects of a session, especially if you have a tendency for back pain or joint pain. I recommend that you take it easy for at least one day after the treatment and pay attention to your posture. Move carefully and avoid lifting heavy weights for the adjusting period. (Go shopping before the session, not right after!) I found that sensitive individuals or people with brain injuries need to plan lots of resting time for the rest of the day as they often feel very tired afterwards. (The energy levels usually pick up after a day or two).
