Been looking through here to find the same problem I have but don't see it.
I have a gas water heater. So here goes.

When I get up in the morning and there has been no use of hot water through
the night,my shower is hot but not as hot as it should be. The next person
to shower later gets plenty of hot water. How do I get the heater to cycle
during the night to keep the temp up

How far is the water heater from the shower? Overnight, the standing
water in the lines will cool off. especially if the shower supply lines
run through an outside wall.
The water heater cycles only when the water in the tank cools off, not
when the water in the pipes cool off.
In my 2 story, 2000 ft house, the master bathroom is almost the entire
length of the house from the water heater that is also two floors down
in the basement. When taking a shower in the morning, it takes a long
time for the hot water to replace the standing water in the pipes and
reach the shower. I usually turn on the hot water sink faucet and the
shower set all the way to hot at the same time to get the hot water up
to the shower faster. Then turn off the sink and adjust the shower
temperature.

I have about the same set up but the water goes cooler rather than hotter

I assume you mean the water gets colder as you run more water. The
heater simply isn't keeping up with the cold water coming in.

How old is the heater?

I have noticed similar problems with water heaters as they age. They
seem to develop a wider range between when the burner turns on and off.

For example a new heater set to 140 may turn off at 140 and turn back on
at 130. As it gets older it may not turn back on until it gets to 110.

For something like that you may be getting 110 degree water in the
morning. The heater turns on but can't keep up with what you are
drawing out.

No adjustment available that I know of. Replacement of the control unit
most likely would not be worth it.

Thanks Rich that sounds like it. The heater is about 8 years old not very
old if you ask me. It's not bad on weekends because I get up and do stuff
around the house using hot water so when I use the shower later there's
pleny. But during the week I hit the shower right away. Oh well at least it
isn't cold water

How can that be it when you said that there is only insufficient hot
water for the first person to shower and that when the second person
uses it, it's OK? If the water heater is not heating to full capacity,
for whatever reason, be it age, malfunction, etc, there would be LESS
water for the second person to shower, not more.

try turning the tank temperature up just a little. the water is cooling
off a little overnite but not enough to turn the burner on again

Unless there is a timer of some kind on the water heater, this scenario
makes no sense. Every conventional water heater I have ever seen has
water that's hottest at the start and it goes down hill from there.

I've tried this but it didn't seem to help
