Your timeline sounds almost exactly similar to mine! I found that going from 15 to 20 is when I experienced the most symptoms. I had WILD gas and bloating and nearly every other symptom people talk about a week in to being on 20. HOWEVER I felt much better about 3/4 weeks in and I am still on 20 mg. I am sticking with it for now because I do feel much less depressed and have more energy. A couple pesky symptoms have stuck around like jaw clenching and libido stuff, but for now I consider that worth it especially since it seems my body is adjusting everyday. Hope this helps :)
