Since you are new to oxys my advice here is based on my recollection of what I did the first time 5mg hit the right spot. There's a mega thread here on potentiation and I've tried a lot of the advice on that with varied success too (not sure how to attach the link for it but it's easy to find the potentiation mega thread from the search page). So my first decent high came from these steps 1)waking up and on an empty stomach chewing up the pill before swallowing, 2)a half an hour after dosing consuming a high fat/extra spicy small meal (as greasy and spicy as I could swing). These two simple steps gave me my first decent high at the one hour post dosing mark (I could time it in the following doses and they hit me within the same five minute window each time). Obviously there are hundreds of scenarios to potentiate and these two steps overall were not the greatest steps ever but they were the first ones I tried and had success with and they are the easiest to implement because they don't require specific ingredients.
