Last night was my second night on Naltrexone. Too early to tell how things are going but I'm feeling good. (Drinking a lot slower and not finishing last beer). Anyway... I went for a cycle this morning and when I got home I felt awful. I just go out for around 45 minutes but I try and push myself with sprinting and that. I do usually feel a bit rough if I'd been drinking the night before but this was worse than that.

I haven't read the book so I'm not sure if this is the norm. Was hoping for a bit of feedback.

Could be. I'll find out with more experience hopefully as time goes on. Exercising is pretty hard even without the Nal with a hangover, it was the queasiness I felt when I got home which was new. It was nothing I couldn't handle though and I suppose you should expect a few side effects at first. I dove straight in at 50mg and have read a bit of nausea might be expected.
