not much advice mate, but stick with it. I used to do it religously then when i got a long hours job I stopped. after this amount of time going mate, your body needs to do a lot more work than a normal person that doesn't go to keep the weight off now, you will pile it back on if you stop. maybe just cut the number of times you go by a bit. but don't stop, you will regret it, I did, i'm now 21 stone. from 15 and a half a year ago.
