For me the sleep problems mostly went away after about six weeks, though I was also taking Benadryl along with melatonin at the time. These days I'm on sermorelin and epithalon instead. Basically you can quit, cut the amount, or just keep going until it passes.
I'm wondering how long the sleeplessness from reta is supposed to go on. It's getting really hard since I get zero rest. Adding tesamorelin hasn't changed anything and even melatonin does nothing. Any ideas on what else to try?
