I sent this email to the good doctor yesterday morning
"Dr. Constantini, as per your instructions in your first email, I am stopping b1 today do to a general feeling of weakness and periods of dizziness which started 2 days ago. If these conditions are relieved, I will restart b1 on September 23rd with a daily dose of 1 gram according to your protocol.
If you have any other instruction please let me know.
Thank you, Danny
He replied with a simple "ok"
I've now missed 4 grams of b1 and already the back pain(see chap. 2) is returning, but the weakness and dizzy spells are subsiding also.
Send me some patience in a bottle.
