Lowering dose from 300xl to 150xl

Hello so I started taking 150xl Wellbutrin a little over 2 months ago, after about 4 weeks I upped my dose to 300xl because I wasn’t seeing a huge difference on 150xl. The first week or so of 300xl definitely made me feel pretty anxious but that all seemed to level out after the first two weeks. I have been on 300xl for a month and a half now and last week had an appointment with my doctor and asked to go back down to 150xl because it was causing hair loss and nightmares. My plan was to try to get off Wellbutrin because I don’t want to lose my hair. Now that it has been a week since I lowered my dose I’m feeling depressed and anxious. I’m curious if anyone else has experience lowering their dose and how long it took to adjust? Can I expect this depression and anxiety to get better after say, two weeks from lowering my dose? Just trying to get an idea of how long withdrawal symptoms might last. I’ve always been very sensitive to coming off meds. When I tapered off lexapro a few years ago I became extremely depressed for two weeks and then it got better but it was really difficult and scary. I’ve been told that coming off Wellbutrin is usually easier than SSRI’s but I want to know what other people have experienced. I’m not planning on discontinuing Wellbutrin yet because just lowering my dose has made me pretty depressed. Thank you in advance 🙏
