Ok, been looking up your side effects, and your Klonopin could absolutely cause hallucinations, unusual risk taking behavior etc. Your Lamictal and Klonopin both could worsen depression - your lithium could be why you feel heavy breathing. You should consider trying some lower doses, or different dosages. Talk to your pdoc as soon as you can, or whoever is prescribing these. Seriously, I had to change my meds repeatedly to find just the right stuff for me. When its right you will know it, and your dosages are such that they should be working, or not. At least, if you look up the possible side effects of each you might feel more empowered by what you are experiencing.
