Yes I am not comfortable with upvoting myself but I'm usually the only one voting on me lol so ...

It's a controversal topic. I would say it's ok to upvote your own posts, and your comments only if you upvoted the post you comment in, and only if its a meaningful comment.

Thanks for the knowledge!

And in fact it is highly recommended by many people who post here. I think the main thing is if there's a general agreement about something like this then it's cool. If it's understood that you vote your own post up then great. It's when some take advantage of it.
