Effects of methyl cobalamin

For the last three months, I am not taking any multivitamins. I have developed right hand pain (due to laptop mouse usage), low back pain (probably due to poor sitting posture and sleeping on foam mattress which forms body impressions) and gluteal muscles pain (probably due to poor sitting posture). So, I tried taking methylcobalamin 500 micrograms once daily for 4 days (two days taken at night and two days taken at morning).

Positive effects:

1. Reduction of hand pain and low back pain
2. Little relaxed mind
3. Tendency to watch movies, listen to music

Negative effects:

1. Not getting sleep in the night - but if I sleep, unable to get up easily.
2. No focus or concentration to do any job - simple jobs took may hours to complete
3. No motivation and energy to do any job.
4. Not able to think deeply - postponement of few tasks

5. No attention to details - errors happened in work

6. Decreased speed of information processing while driving


30 hours after the last dose of methylcobalamin, I felt return of energy and focus.

Severe headache and ibuprofen

I had severe headache after consumption of becosules Z capsules (just one dose) and applying betnovate N cream for two days. The severe headache may be due to the presence of 100 mg of niacinamide in becosules z capsules. I used to get headache while I was taking niacin before. The headache was right sided indicating that it may be dopamine deficiency-induced. I took 400 mg ibuprofen at midnight. After 40 minutes, the headache disappeared and slept nicely. Earlier, I used to take dicolofenac for such headaches or paracetamol. Diclofenac used to be very effective but due to its enteric coating, it will work after 4 hours only. Paracetamol 650 mg or 1 gm may afford some relief with residual mild headache continuing for next 1-2 days. Ibuprofen seems to be effective. But, I had some stomach discomfort after taking the tablet indicating its ulcerogenic potential.
