Yes! I also am sooo tired throughout the day. I believe it has to do with all the meds we are taking...or it may be a symptom of CRPS. I guess I'm really not sure, but I feel your exhaustion. Going from having a "normal" sleeping pattern to a very sporadic nights sleep can cause all kinds of problems. I've heard that people who have RSD (or chronic pain) rarely reach the REM cycle during sleep...which is necessary to function properly and to think clearly during the day. So, my GUESS is that not reaching our REM Cycle at night mixed with all meds we have to take during the day makes for an exhausting combination!
