I started Tymlos a couple of months ago. Day 1 was 20, day 2...40, day 3...60 and day 4... 80. The morning following the 80, I had a severe headache. I continued on that dose for about a week suffering headaches and light-headedness each day. I contacted my doctor and he reduced me to 20 each day for a week. I did okay. He then increased me to 40...every other day. I've tolerated that pretty well with only mild wooziness at times. Did that dose for 2 weeks. He now wants me to do 60 everyday. I didn't make that change and have actually skipped some doses as I was having company for a few days and didn't want side effects to ruin that. The last few days I have had pretty bad lightheadedness throughout a good part of the day with no Tymlos and now wondering if I'm having withdrawals!!...and now anxious I have screwed up!!! I take mine at night. I also would like to know how not getting the full dose impacts my whole treatment plan.
