A lot of my problem is I slowly became increasingly dehydrated over the course of the trip; day by day. Plus doing two 1-1/2 hr dives a day, was probably pushing it a bit much. I rested for a couple days & got myself rehydrated, before doing some simple rec dives & was fine. I have also changed the way I dive a bit. I now only do 1 "big boy" deco dive a day & the second dive is typically a no deco "weenie" dive in the afternoon with a minimum of a 2 hr surface interval. I have not had any problems since then. When I began tech diving, my tech instructor told me, "In tech diving, it is not a matter of "if" you will get bent, it is "when", seems to hold true. One just has to know their limits.
