Day 1 cellcept

I took cellcept last night for first time. I also took Xanax because a bit anxious as far as what will happen next. Went to bed at 10 and woke up at 7.  So full nights sleep.  Woke up this morning feeling very sleepy. My arms feel like lead weight and chest hurts by incision. I ate a cup of Greek yogurt and see what happens. I know I'm still weak from lack of nutrition. Hopefully will bounce back as day wears on.  My oldest son has his junior prom last night. My husband said he saw him returning from post prom this morning. He said he had fun. Hope so, will find out more later.
