I will report back after the first month. I wanted to comment though, be careful not to take it late in the day. I've been sleeping in lately and take it after Noon. This stuff keeps me up past 4 AM. Yesterday I decided not to use it to try and regulate my sleep pattern. I also did not use any Tyrosine either. What a mistake! I was moody...lashed out at my brother over something petty. I felt tired, down and had no motivation. I was up until the crack of dawn anyways. This morning, I felt horrible! I felt depressed, anxious, tired, moody, you get the idea. I took 2 drops and 1 gram tyrosine and I feel amazing again.
I normally feel the effect of reduced dopaminergic activity. This is something I have to continually tweak to be functional. I wonder if my experience was that, or maybe deprenyl has some kind of rebound effect. But I doubt it. I might stay on two drops for a while. I am 30 years old but I know I have problems with dopaminergic function (i.e. NO motivation, social anxiety, etc.) I hope that's ok.
Well, it's almost eight years too late responding to you, but in the literature taking the MAO-B inhibitors like L-deprenyl together with a dopamine enhancer (usually it is L-Dopa) has very bad outcomes. I believe the research reports have been that this combination shortens life as well. While I doubt they tested tyrosine specifically, I still think that is cautionary. I would choose one approach or the other, not both.
8 years! Thanks for the response anyway. I remember this event well. Deprenyl stopped working after using it a short while and put me in a rut that lasted a while. I fazed out of it eventually.
