<s>[INST] I have a TBI and have problems with muddled thinking.  I was taking my Toprol at 9 a.m. at work and at bedtime.  This week I changed the time for my morning Toprol to 1 p.m.  This seems to have improved my focus and concentration at work, but now I am muddled after work.  Would more  COQ10 and/or omega3/6/9 help this?  Is there anything else that might help? [/INST] Hi, Thank you for posting your query. Cognitive symptoms following traumatic brain injury (TBI) spontaneously improve over time. However, COQ 10 and omega 3 fatty acids may help (there is no hard data in literature though regarding their efficacy). Another medication that could help you is paracetamol. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/ </s>
