@locoyeti I also had crazy experiences with 400mg
if i can take 400 with dinner, high, but ok, but then i wake up at 5am or so to take another 400, this time stomach was emptier, but well just went to sleep, i had a crazy dream that made me woke me up, there were like 5 children, i woke up, and when woken up, turned on the light and i was very convinces that thanks to that dream i could predict the future of that children, well that was maximum highness...
but on that moment i was hearing some repetitive sound (like yours), very strange, and also I had Visual Hallucinations with open eyes (for first time), saw some tubes that went throw my jacket. Its like when you wake up from a dream on top-high state, you wake up and I still dream after wake up, (its the 2nd time it happens to me)
So well, that sound, I dont attach to tinnitus, its a sound-hallucination, as same as i had visual hallucination, thats why that doesnt occur to me on 300mg, 400 on empty stomach is totally killer, maybe as my T improves I can reduce the dose to 300 to get silence, because there is no point to take 400 if i get silence with 300, will see how it goes... maybe is good Idea to take that 400 dose mixed with a banana to do more progressive absortion
