Switched to GetDopa from taking a daily Magnesium supplement as it had been recommended, and contained the same amount of Mg along with the other contents. While more expensive I had high hopes. What a let down. I took these for 2 weeks. In that time my energy and focus was destroyed to worse than taking no supplement at all. I couldn't remember the simplest things. I began to experience nightmares every night. At the point where I ended up sleeping all day sunday I gave up and switched back. Instantly better sleep. These might work for some people but they did not do any good for me.
