These are serious dives, very close together with really little surface interval, especially considering the depths and times. I am amazed that your computer even let you back in the water after the first two Saturday dives (assuming what you said that the times given were bottom times, not dive times).
By the way, a friend did some very aggressive deep dives on the wreck of the aircraft carrier HMS Hermes in Sri Lanka and he ended up being affected by the high oxygen levels used on deco so that he no longer needed to use reading glasses for about four weeks after the end of the diving.
