Can I experience side effects again when I return to trittico? I took trittico for about a year, for the first few weeks if I woke up at night (e.g. to use the toilet) I felt very bad, my heart was pounding, my legs were soft, my breathing was becoming restless, I had the impression that I was going to faint, after a short trip to the toilet I was going back to bed and I felt like I had just run a huge distance, I didn't stop taking the medication because I had a lot of problems with falling asleep and nightmares and in this matter I felt a huge relief, I just made sure not to wake up at night, then everything passed and when it happened that I woke up at night I felt normal. For the last three months or so, instead of trittico, I have been taking pregabalin and then miansec, but none of them worked, not only when it comes to falling asleep, but also my anxiety attacks on a daily basis have returned, the doctor suggested going back to trittico, but I wonder if when I take it again after 3 months, the side effects like the first use will appear again. I'll also add that back then I was taking escitalopram for it, and now I've been taking bupropion for a few months now and it's working much better.
