I notice you listed niacin in your supplement list.

If you are taking real niacin ...that can cause skin paresthesias and tingling flushing etc.

Niacin in the form of niacinamide does not cause this reaction.

Thank you for your knowledge. I have read many of your posts, or did so prior to joining. you are a light and inspiration to many.

I am glad to say that I'm taking niacinamide forms

Update:
=========

I noticed some muscle wastage across upper pecs, forearms, biceps, which has been arrested by B1 incrementation.

Added iron on noticing some breathlessness after running.

Added zinc and drinkable (non acidic) vit C.

Right then... Past three days, very very few paresthesias.

Friday - no paresthesias, but incredibly fatigued. Longest sleep in months, woke up to wanting more sleep.

Saturday, Felt about 50% of the degree of yesterday's fatigue. Managed to do some light runs. Felt like hell afterwards. did a bodyweight circuit, 100 lunges in 6 minutes ( 40, rest, 40, rest, 20) made my legs feel like lead. Then followed up with 30 minute stationary bike cardio dealy 4 hours after that.

Sunday, A lot less fatigue, some vague tingling in left sole, very light "cobweb" feeling back of right hand. Very brief 5th cranial nerve region feeling of being touched by a ghost (on cheek).

In the middle of completing a two hour work out.

Belated Happy Easter to Ukrainian people and Egyptian people, and to all and sundry who observe the orthodox calendar. Belated Belated Happy Easter to all who observed the imperialist calendar a week ago.
