Andre and I are coming across some new "symptoms" and we are a little confused by it. When he was originally dx the dr said it was N with out Cat. Over the last 4 to 5 months Andre has developed Cat like symptons but only after sex

. It's not always the same, sometimes he can get back out of bed and continue his day other days he just suddenly hits a wall and can't get going again for a while. Usually if he takes a nap he feels better but still has a rough day. At his appointment this morning the dr said it could be Cat attacks since its a loss of muscle control just not severe.
So my question to all of you is can you be dx originally with out cat attacks then over time develope them? And if so do the cat attacks get worse?
The dr also changed his script from 200mg of provigil daily to 200mg in the am and 100mg about 4-6 hours later and added 20mg of prozac.
