how are you mate,
your doing pretty good ahh, that's good, your fairly comfy at 18 ahh!
i think ...you need to gently build on it now, ( only you know you ), others are right, but everyone will have a different opinion, cos were all different
it sounds real good to me,
but, it can be tough out there, every day can be diffierent, depends how your mind is
you can either , get your body used to 18 and 20, or try pressing on gently now
best of luck, everyone is with you
