Feeling crummy post thyroidectomy/I131

Hey all, new to the group and somewhat new to this whole thyroid cancer thing. I am a 32 year old female, diagnosed with papillary thyroid carcinoma (nodule was incidental finding at annual exam, aspirate confirmed PTC), had total thyroidectomy April 27th (no obvious metastisis, no parathyroid complications post op, calcium levels normal, surgery was uneventful). Started 125mcg of Synthroid once daily in the morning the day after surgery, received I131 treatment March 25th (did with thyroid injections prior instead of having to go off Synthroid and be hypothyroid for several weeks prior to treatment), full body scan done June 1st (looked clean to me, but have not gone over results with Dr. yet). I have thyroid bloodwork recheck scheduled for this Wednesday and then will meet with my endocrinologist on Friday to go over body scan and bloodwork results.

While I am grateful that this is not a scary cancer (compared to others), I am dealing with some side effects/symptoms that have affected my life and activity level. I just want to know if others have experienced them as well, if they went away or what has worked for you to decrease frequency/make you feel better.

1.) Since surgery, I have had 2-5 migraines a week which I can control with Excedrine Migraine medication, but the migraine and drugs make me feel very blobby, foggy brain and lethargic. I have had occular migraines since I was ~11yea that tend to be related to my mentrual cycle/hormones, but generally would get one ever 2-4 months. These new kind of migraines are not the same but still result in debilitating pain and nausea I don't catch them early and take meds. Has anyone else started having migraines post op? Did they improve once your synthroid dose was regulated? What have you done to decrease them?

2.) I am tired ALL THE TIME and have no appetite. I was a pretty active person before all of this and one of my favorite things in life is food. Now I take a 2 hour nap (at least, if I have a migraine, it will be longer) every day plus getting 8-9 hours of sleep per night and I fatigue quickly during activity. I have no motivation to exericise, which is really out of character. I suspect that I am hypothyroid, but have not had my levels checked yet. That being said I have seen many others on these boards who also have severe lethargy despite normal T4 levels. What have you done to increase energy? Are their supplements you have had success with? I am fine looking into alternative therapies/ideas. I am not having weight gain (thank goodness), but I am also not eating much because I am not hungry.

3.) The day after my I131 treatment, I had significant swelling and discomfort of my salivary glands for about 36 hours. Symptoms improved with Tylenol and there have not been long term effects in that area. However, starting a couple days ago, I have progressively lost most of my sense of taste (which I have read can be a side effect of I131) and have a metalic taste in my mouth. Nothing has flavor, which really bums me out (salt and sweet are both pretty much gone, sour is also not very prominent). Have most folks gotten their taste back within 6 months? Was your taste permanently changed? This damper on my love of food is totally kicking my puppy.

Really appreciate any feedback. I realize that my issues are "1st world cancer problems" and I am grateful that if I was going to get cancer, it would be PTC. That being said, I feel like version 1.0 of myself, and want my life back. I want to enjoy the activities I did before surgery, I want to have energy again and I want these freaking migraines to decrease in frequency. Any advice or insight is appreciated.
