For me , it goes like this 15 ug dont feel anything at all 18 cant feel anything most of the time , but i can tell i am on smth when i need it , fe . in school when i have 6 hours in row , i can keep focus all the time wo problem . 20 seems ideal to me , i have good mood all day and can really benefit from effects 22 similiar to 20 , just now I can feel little comeup , otherwise everything is ok . This dose effects the way I listen to music , it becomes more clear and much more fun to listen . 24 most similiar to 22 , all aspects are same , but sometimes its too much , that means instant mood changes without reason and small distractions . Tried this dose once , not doing it again Well , that would be it . Most of the time i dose 20 or 22 , based on how my day is going to be . If i have some free time to enjoy music , 22 is way to go . Otherwise when i know i will be stuck whole day at school , 20 will be just fine . I dose 23 times per week , usually one day off . Days between are ok , still have good mood and no depressions nor anxiety .
