Hi is sugar free methadone lighter than normal methadone and how can I tell if its watered down I shook it and looked in bottle and no bubbles stayed at the top same with pouring it, the normal methadone has a really strong cough syrup i get off him he also sells me 50ml methadone which he says is his girlfriends it does hold me but wondering if it is sugar free or watered down as I need atleast 35ml to be ok all day even though 30ml and a 10ml in evening works better.
