First of all, I don't understand why you are being prescribed any SSRI medications because they tend to trigger severe mania in people who have bipolar disorder. A mood stabilizer would seem more appropriate for you, perhaps prescribed with an antipsychotic. I would speak to your psychiatrist about this, or perhaps consult another psychiatrist, but everything I have learned from books on bipolar disorder and from my past psychiatrists and treatment programs says SSRI+bipolar disorder = bad things usually.
A lot of people who initially seem to be suffering from unipolar depression get prescribed SSRIs, go manic/psychotic, and then that's how they find out that they actually were suffering from bipolar depression.
As for drugs, since you have a very serious mental illness, don't you think that you should quit psychedelics and everything else for, well, forever? What's more important to you? Being able to have all of your freedoms and live your life as you want it or being shuffled in and out of mental hospitals? No one knows how you are going to respond to drugs since every person with bipolar disorder has a unique case; the severity of symptoms and the rate of cycling varies from person to person. Psychedelics could be the worst possible thing for you to put into your body. It could be weed (weed tends to trigger manic episodes, too). Sure, there are bipolar people who still use, but just because they can get away with something doesn't mean you will. Also, you could be fine for a few months and then BAM suffer the consequences of regular use of your DOC. It's up to you to do what you want, make your own choices, but be aware that very bad things could happen to you if you keep using.
As for side effects, give the medications a month or two. Usually side effects will go away after this amount of time. If they don't, talk to your psychiatrist about altering your dose or safely switching to a different medication. It can take a month or so before the medications you are on even begin to work and have a chance at treating you. You're going to have to get used to staying on your meds and taking them, even if you feel "fine" for a long period of time. Bipolar disorder is a lifelong condition. Exercise, proper sleep cycles, and a good diet go a long, long way, but they aren't enough on their own to treat the symptoms of bipolar disorder.
It could very well take you years before you find meds/combinations that actually work for you. It took me a damned long time, but I've been totally stable for going on three years now. You have to go through a lot of bullshit to get to a good place, but in the end it's worth it. Believe me, I'd love to trip and get high on pot again, but I know that's only going to send me back into the hospital so I don't do it.
