When you get ready to descend exhale all your air, when you breath in dont take in a full breath, only take in a half breath, when you exhale this breath, exhale a full breath again. When your at 10 to 15 ft dont take in full breaths take slow half breaths. This is were people have their problems, because the deep breaths will float you back towards the surface. Another trick you may try is flood your suit, it is possible you may be getting air pockets in your wetsuit. So what you can do is grab the neck of your wetsuit and pull it out to let water inside and this will fill these pockets, helping you to sink. Trial and error.
