I think the sleep apnea thing has been covered...you know you have an issue so get that treated and you also recognize you are chronically dehydrated...so easy fix there.
If you are randomly taking 300mgs of test it's impossible to know anything from your test levels on this test. It's almost irrelevant. Maybe it's great, maybe it's not. With that decently high dose, but at random times, there is just know way to get any useful information from your test levels.
If I were you, I'd go on a 2-3 times a week dosing pattern with weekly dose around 140-200mgs and then you can get a test reading that will tell a better story or advise you properly.
