I had a ten+ hour panic/anxiety episode on Halo. I was out of town and hadn't worked out in two or three days, wasn't sleeping well, and couldn't get to a doctor in "my circle" of covered insurance docs for at least 15 hours which probably freaked me out worse. I got back into town and went in. I got bloods and my liver etc was fine. Heart looked fine. Either I was freaking out and anxious for nothing (likely my psych issues then) or I have an underlying physical issue that has never been found in my history of injuries and hospitalization (motocross) including immediately following this episode (not likely IMO).
I'm going with anxiety freak out.
I ended that cycle and saw the doc but everything was fine so I plan for more future anabolics. I have to start slow, bump up doses gradually, and tell myself I'm fine this crap isn't going to kill me (short term). It's the rapid changes in what I'm feeling and my body thinking something is wrong. Go slow maybe you can fight through.
If I keep having issues with orals I think I'll switch to pinning for the steady levels and a compound my body knows (test)...
