I stacked DSIP and Epithalon together. The first 2 nights, I did not sleep, I became sleep deprived. I took DSIP up by 100mcg every night until I was at 400, Epithalon stayed at 500mcg I changed my dosing time to 2 hours before bed and it made ALL the difference! I go to bed, fall asleep and wake up 7 hours later ready to go! I don’t ever remember waking up feeling rested, ever! Now I wake up ready to concur the day. I have 1 week left on this stack. And the best part, I’m 100% off the Trazodone for sleep.
