You really got a hold on me

Great! I wanted to say something like this, but I couldn't formulate it. I completely agree with you. This is, in my opinion, why he really put the Ring on in the end. I think also something like this was from time to time happening to him on the road (apart from the moments he really wanted to hide or escape, but this was more at start, when he still didn't have that much experience with what the Ring can do) - the pressure was so big, that it was easier just to give in.
The interesting thing about this is, that where there is no knowledge of trespassing something, there is no temptation: if you look at Bilbo, during his adventure he was putting the Ring on and off with no problem. Of course, it became later something like a habit, or like addiction to smoking: he was not comfortable when he didn't have the Ring with him. But during the adventure - for example in Mirkwood - he had the Ring on for several weeks - some think that it was a month - without putting it off! (in Thranduil's halls) If you consider that it was the Ring of Power which he had... on... for a month...
