Getting worse at chess puzzles instead of better?

You know I used to be 1380 on lichess and stay that wya on medium puzzles, now I am down to 1200. I just can't solve the puzzle first time around. Sometimes these puzzles give good moves but you can do better, but lately i haven't come across those.

Should I try puzzles on a different website?

u can try chesstempo I need to go there as well
since ive only played one day and have my account unused,
the good thing about chesstempo its that u can see the comments of other players if u dont understand the puzzle,
plus they use terminology and they are well made and from real games, so yeah its a good idea I gotta do that as well
since I have not and its what I need to increase my tactical ability
so thanks for the reminder dragon
here its the website

Chesstempo,

If you guys figure out the java thing that allows the engine use, let me know. I spent several hrs on that with different browsers, updating java, disabling all security in browser, allowing all plugins, etc. Tried firefox, IE, chrome.

Chesstempo is awesome for tactic puzzles, as well as endgame puzzles.
I would suggest you start doing standard and mixed mode puzzles on chesstempo website (ignore the blitz tactics unless you reach something like 1700 tactics rating there.)
It is important to keep the routine.
Doing 100 puzzles in one night, and then 2 months nothing is unlikely going to help you to improve your tactics.
I have been doing tactic puzzles on chesstempo since around 2011, and it is interesting to see that several puzzles that I failed in the past I am now solving successfully. On the other hand, some puzzles I solved in the past I fail now, but that is just a few.
Regarding rating : my chesstempo standard rating goes up and down between 1850 and 2130.
I try to do my best to not give that rating too much value.

There's thousands of puzzles, and I also sometimes do those puzzles when I'm tired and bored. A fresh and energetic mind will likely give better results when doing those tactic puzzles.

But try also the Ideachess, Emrald and Chesscademy tactic websites. It is a good idea to not do tactic puzzles on just one website during a few years. You will probably also see different ratings on different websites.
