Does anyone else experience significant weakness and fatigue for weeks after your vaccine?

I am on the first shot of Covishield and started losing strength 2 days post-shot and it has never improved. I'm due for 2nd dose next well and concerned.

I have not found any information that side effects last more than a few days and I’m at weeks now.

I had covid 6 months ago! I still have a less acute smell and altered taste. I know how food should taste and smell. I have read that there is a nerve that becomes inflamed and it can take some time to get back to normal. But am wondering WHEN?! Will it be like this forever? I do smell 'some' and taste. But it's not back to normal.
