No ch hit yesterday, no shadows, no ch pressure on right side or presents of a ch, an awesome day for me, slept all night the last two nights, I'm having positive results, yesterday took 100mg x4 through out the day, still researching how B1 is acting on ch, found this last night " B1 helps the production of cellular energy and has a calming effect on histamine related headaches ". I had a dexalog shot in okc and it had a B complex with it, not sure of dosing.
