Seroquel works very well for me at 25 mg at night. It also lowers prolactin a bit. The remeron mentioned by
@jJjburton is structurally similar to Seroquel, and displays antihistamine activity, which might help with tren-induced indigestion in addition to sleep.
One issue with this approach is that, once these sleep aids are started, the body can become dependent on them, so tapering off is necessary.
This is the problem with tren: I have to do too much extra shit in order to use it. My next tren blast will be my last. I'm too old, and it's a young man's drug.
