Tolerance Question

i been taking 7 for about a month and a half now everyday seems to say i lost the magic and euphoria from it even the sedating part is short lived i use anywhere from 200-400mg daily (400mg only some days not frequent) i was wondering if i dropped down to 25mg-50mg range for a few days will that reset it ? looking for all the answers i can get its starting to become not worth it anymore and i refuse to go higher then 400mg ever i just miss the spark it gave me i need advice
