Now I was wondering because I saw someone post about this resently and I have had this happen to myself so I know what it?s like, what I?m talking about of course is when u just can?t get that euphoric feeling anymore from ur drug, like I understand tolerance is the problem but at what point does tolerance go from ?ur gonna need to take More if u want to Get high? to ?nope sry no more euphoria no matter how much u take? like what?s happening in ur brain at that point? I?m honestly really on the edge of my seat as to what the exact reason is for this because I really do like understanding stuff with how ur body works and why certain things happen and this falls into that category so let me know even if it?s just a guess (an educated guess that is). Thanks for the responses
