I joined this forum because I am having similar issues and can't seem to find a solution. I have been diving for almost 20 years and am in great physical shape. I am very conservative with my air and have always had perfect buoyancy. In the last few years I have had an impossible time controlling my buoyancy, adding more weight, trying to adjust my breathing and constantly fiddling with my bc didn't help, the DM had to hold me down multiple times. I appear to be negatively buoyant and have no trouble descending, but 10-15 minutes into a dive I am literally fighting to stay underwater. My last two dives I had to hold hands with the DM. It guarantees I wont miss the boat, but if anyone has some suggestions I will be diving later in July.
