I've used MT2 several times for many years dating back to 2007. After a two year break, I just started my first vial from a new-to-me supplier and have insomnia. After a bedtime injection (.25mg) I wake up after a few hours and can't go back to sleep. This is such a low dose...I'm perplexed. The nausea is fairly strong, too, even at this low dosage. Anyone else deal with insomnia? Thanks so much.
