I started vinpocetine about a week ago because I recently started having tinnitus in my right ear and I'm trying to see if I can stop it (this will be another thread).
I am very sensitive since certain supplements seem to have a big effect on me, so I began with a small dose. I am using 10mg tablets. Source Naturals.
Day 1: 2.5 mg
Day 2: 5 mg
Day 3: 7.5 mg
Day 4: 10mg
Day 5: 12.5 mg (10 mg in the morning and 2.5 mg in the afternoon)
Day 6: 15 (10 mg in the morning and 5 mg in afternoon)
Day 7: 17.5 (10 mg in the morning and 7.5 mg later)
As of a few days ago I started getting sleepy in the afternoon. I also noticed I had a slight headache. I have not noticed any change in my thinking or anything and if anything my short term memory might be worse than usual.
Tomorrow I am planning on taking 10mg in the morning and another 10mg later, and am going to stay at that dose.
Does vinpocetine require choline like piracetam so you don't get headaches?
The only other thing I thought of that might be causing the sleepiness is I've been taking magnesium taurate each night before bed, which does make me sleepy, but that's why I take it at bed and I don't think it would affect me the following afternoon especially considering I don't feel sleepy until a few hours after I've been taking the new one.
The only other things I am taking are Lipoflavonoids, which I've been taking for over a month and they don't make me sleepy, B12 which I take twice a day and I've taken it before and it doesn't make me sleepy, and 25 mg of zinc which I take in the afternoon and probably isn't the cause.
Have any of you experienced sleepiness from this before? Is there a period where your body get used to it where you get sleepy or headaches?
