Thanks for your reply.  What I meant by the every other day was 15mg one day and 20mg the next not on and off meds completely.  But you are right a steady level is probably better. 

I tried the dex.  I was taking .25mg at bedtime.  I seemed to run out of gas in the afternoon.  I feel like the HC is more physiologically compatible.  I also feel like I have a greater ability to adjust the dose as needed.  For example, if I am playing a competitive tennis match, I will bump up the dose so I don’t bonk before it’s over.  I guess this is just a juggling act.
