2 weeks before I took a stack for cognitive improvement and now I have like akinesia.
Here is the detail:
Betahistine acts both as a partial agonist of histamine H1 receptors and as an antagonist of histamine H3 receptors, also in neuronal tissue, and has negligible action on H2 receptors. Betahistine increases the turnover and release of histamine by blocking presynaptic H3 receptors and reducing the number of H3 receptors.
And also seems to act on dopamine: https://www.ncbi.nlm.nih.gov/pubmed/25149912
2) Phenylpiracetam approximately 250 mg + n-acetyl-l-tyrosine 300 mg
Thursday 2 weeks before: I have betahistine and multivitamin at breakfast. About 2 hours later I took Phenylpiracetam and tyrosine. I got a very good focus at work and a mood improvement like never during the day. No side effects. In the evening I took ziziphus + melatonin to sleep.
Friday: exactly the same protocol with the same effects
Saturday: no stack but I took cdp-choline at the same time as melatonin before bed to reload choline from phenylpiracetam.
Sunday: very strong headache from waking up all day. I just took paracetamol 3 times until bedtime. evening zizphus + melatonin.
Monday: no more headache. I repeat exactly the same protocol as Thursday with the same effects except that late afternoon I feel the legs as "very heavy" that lasts until bedtime.
Tuesday: I just took tyrosine + multivitamin. slight boost and late afternoon heavy legs. I stop all the supplements. just melatonin in the evening.
All week I had muscle fatigue (very heavy leg)
Friday I go to the gym: when I train I feel like muscle fatigue and jerks during movements with lower performance. I have trouble finishing my training.
It was like this I was in permanent hypoglycemia (muscle weakness and slight trembling). I have barely visible tremors on small movements (take a cup of coffee) and when I walk. My movements are slower.
Today all this seems to be worse.
At the cognitive level sometimes I have to think to find what I was going to do. No change in the mood.
Sorry for the long post but I am very very worried.
Do you have any idea what it might be?
What can I do ?
I have 9-me-bc. Maybe that can help? (but I am afraid to take supplements in this state).
If not, what can I take?
I wait a little to see if it passes but if it continues I may go to the doctor.
Please help me!
Thank you so much.
