Hi, I started a bit of a miss-match of the methylation protocols approx 6 weeks ago and for the first month I was taking a Thorne Basic B Complex (which contains methyfolate) and half a Jarrow B12 sublingual daily. I noticed improved stamina and lessened fatigue but no other improvements or indeed side-effects/detox symptoms. I then decided to replace the Jarrow B12 with half a hydroxy B12 tablet. This brought with it reduced inflammation but sadly also pulsatile tinnitus and a 'full' feeling in my ears. I continued with this regime but at a lower dose, only 1/4 of a hydroxy tablet daily along with my Thorne B Complex. The pulsatile tinnitus then became intermittent. The reason I'm posting is because a few days ago I introduced 1/4 of a Source Naturals dibencozide B12 tablet along with the other supplements. Immediately after taking it my tinnitus skyrocketed and a few hours later came the eye fatigue. I was unable to focus all evening and had feelings of extreme eye strain. There was no reason for this, I hadn't been out in the sun and I hadn't been at my computer. The dibencozide was absolutely the culprit. I have had none since and now, on the fourth day later I still have a feeling of 'eye strain' and my focus is better but still not perfect. Will this go away or is it a sign I need more/less B12? Or more/less folate? The fact this happened after taking dibencozide makes me worried as the side effects still haven't passed.
