There is a maximum speed you can cycle home at after - I found this last Tuesday, my heart was racing and I got an ache in my chest. Think next time I'll just go back to taking it easier!
Drinking lots of water before and after us for the best.
As for booking appointments, it's no hardship, at the session I book up for the next one, stick a reminder in my phone and job done.
And last session I had to wait a while to get seen, but sh*t if if saves a life what the hell do I care. People take different times to bleed, the staff that work these sessions are doing the best that they can, they are, as has been said all great people and I'm assuming aren't on massive salaries, they work outside regular hours to make it easier for us - GIVE THEM A BREAK. Nearly shouted that at a woman who hadn't booked and was whinging about having to wait last time.
