Lately, often in mornings, I've been experiencing these awful spells of dizziness. I don't know if it's a sudden drop in blood pressure or what. All I can do when it comes on is lie down. Have NO energy....not even to speak. I can only hear what is going on around me and breathing tends to get more deeper/quicker. It lasts for several minutes. Is this a fibro symptom or could it be the Cymbalta I've been on for 3 week now?? Thanks for any input!!
