Hopefully others will chime in - but assuming the sleep interruptions/feelings of doom is due to grief rather than the meds, my side effects have been minimal. Initially it caused insomnia (a very unusual side effect). My doctor then recommended that I try taking it in the morning instead of at night - but I only did that once because I totally zoned out for hours. I played with timing and having discovered that taking it around 8 PM gives me the best results. I can stay up until about 11:30, then I need to go to bed. When I'm not experiencing the feelings of doom, I sleep like a baby. I think I also experienced a kind of 'tugging' on my shoulders for a couple of hours after taking it every night - but that seems to have disappeared.

Personally, not really. I struggle with fatigue- but I’m on a lot of meds and in combination with all of my medical issues that’s normal. But as far as side effects such as others have mentioned, no- not at all.
