I've had this issue and my physical therapist was able to walk me thru the steps shift the crystals back into place. You can try looking on WeMD for those steps, I think they have some good instructions that you could use. And if you feel you need to take something, you might want to try motion sickness over the counter meds. That's what my doctor suggested for this particular problem. Basically the crystals in your ears help tell your brain if you see things as if you were in an upright position or a sideways (like laying down) position. When the crystals are move around in an area they aren't supposed to be it's like one second your standing upright and the next your laying down and your brain has to catch up to that information. That is where the dizziness comes in.
