I am no doctor and don't pretend to be. What you describe is just as it is for most everyone using chronic sativa. It's the nature of sativa to be light energedic, and light headed is part of it. I don't find much pain releaf with sativa's. Because you are new you must find the right dose yourself. Maybe more maybe less. You might want to try an indica. A heavy effect with maybe more pain releaf. Too much and it will put you on the couch for awhile. Be carefull everyone is different and this med may not be for you. I can not take any thing with codiene. Makes me sick.
