Okay, I've been on CTX (200mg) for two weeks and Pred (down to 17.5mg) for the past week. I feel like crap. Some nausea which is probably the CTX, but also just weak feeling. The least little exertion, like taking a shower, wipes me out. Nooooo energy at all. Any ideas? I'm not sure if I need to call the Dr on Monday or just keep riding it out. Is it a case of you got to feel worse before you feel better? Thanks for any feedback.
